Could the afpub format ever become the standard for different types of programs?

[Ben Wiens]

Introduction
I started another similar post titled "Using Affinity Publisher, Designer, Photo V2.40 as a Swiss Army knife program", but in this post I ask the question differently, could other programs use this same file format? And would Canva ever allow that? Canva could develop these other programs also.  

The afpub file can handle text, vector, and raster and so could be used in all kinds of programs
There would be a big advantage in the world if the afpub file format would become the document standard in the world. It is proprietary but other proprietary file formats have become very standard like .doc, cdr, and indd. Imagine if the afpub format replaced both the docx and pdf format. The afpub file is no bigger than the pdf but the file is completely editable. This means that the same file can be used for editing and viewing just like the docx format. But the afpub file handles text, vector, and raster formats much better than docx. Also the frame based desktop publishing format results in much easier complex formatting than the word processing format. If an IFilter was created so that on the fly thumbnails and previews were created in Windows Explorer or The Finder for Apple computers, this would allow fast viewing of multiple files and multiple file text searching would be possible.

Why should afpub become the document standard in the world?
The best file format is the one that could become the most popular. The afpub files are small in size. They handle text, vector, and raster formats very well. The files are very fast to load. The programs needed to open them are reasonably lightweight. Some people think that only open source and free to use file formats should become standards but it takes teams of many people to do this job properly and create a reliable relatively bug free program or file format.

All kinds of programs would be possible with afpub file format
Some people think that Affinity Publisher is too complicated for average office workers to master. Canva or other software companies could develop simpler "light" programs for text, vector, and raster creation that had the same file format but were less complicated. All kinds of plugins could also be created also. Note taking programs similar to Obsidian could be created using the afpub format that would handle text, vector, and raster formats in one file, so no links or attachments would be needed, every note would be a single file. Everything done in a normal office would use afpub, notes, letters, reports, user manuals, papers, and books could be done in the format. 

Why do I care?
I'm a futurist partly and like to both predict and promote things that makes sense for people to do in the world. Plus many other people are asking the same question, because they don't want to learn a program or create files if clients aren't going to want that. Popularity breeds more popularity. Presently we have Microsoft Word, Adobe Acrobat, and Adobe Indesign, Illustrator, Photoshop that are standards in the world. Microsoft Word handles anything more complicated that plain text paragraphs poorly. Adobe Acrobat has line returns in text and so can't be used as the editing file format. Adobe Indesign, Illustrator, Photo files are far bigger in size than is necessary. The world would be a more efficient and productive place if the afpub file format replaced all these. The more people that use the afpub file format, the more likely that extras would be created and the more likely that this file format would become more popular and the more likely this file format would be around for many years to come.

P.S.
I did buy the Affinity Suite about 3 weeks ago and already recommended it to my brother who is working on another book, and to two people at a funeral I was at yesterday, one who is also writing a book, and another who has just started a graphic design business.
