I work with both the printing industry and laser engraving and both require 1 bit files. The fact that this is not going to be supported is giant. I wanted to like Affinity over Adobe, but this is making it so I have to use yet another program to do something that Photoshop can handle in one. A true 1 bit output would be a start, but won't be a complete fix because every time there is a color conversion (to grayscale then back to 1 bit) there is the possibility of weird and unexpected things going wrong.
