You can access Pantone spot colors from the pull-down in the Swatches panel. You can successfully apply spot colors to vector shapes and type. However, you cannot apply spot colors to gray-scale images (as you can in InDesign) without them converting to CMYK.
Publisher does not have the ability to preview color separations. If you own a copy of Adobe Acrobat Pro, you can open a PDF export from Publisher and check color separations in Acrobat Pro.
The Affinity Suite holds out a lot of promise for those eager to escape the subscription costs of the Adobe Suite, but there remain feature holes, and the development team is small. I think they're a bit under water, and have trouble filling in all the holes in a timely manner.

Yes, I know that they will announce when it's fixed, but for vector program this is unacceptable. I'm using CorelDraw to do my work (with Adobe CS6, SAi Flexi, and other specialized programs for rip/print/cut/engrave stuff), so I do not use Designer for serious work, but I bought it, and support it in my place of business. But this bug is now running joke. Vector program that is not precise is not good program, especially if your work depend on it. Even free programs that come with cutters nail this down (Graphtec, Roland, Gerber Omega...).
I hoped they did mitigate the problem with all other improvements they did (program is 400MB bigger in size then 1.6.1 version).
Also, you would think that you can bypass problem with this method, but I'm doing machine cutting, and regardless that you see clean line in Designer, it's broken at export (for other programs that follow standards it's unusable).
Look kind of OK, but it's not OK, not at all OK.

Just to report that Expand Stroke function still suck.
Check attached file, and zoom in first on top one, then on bottom.

I use expand stroke a lot in my illustration with apple pencil pressure curves (i have to expand all of my outlines for microstock).
Expand stroke is an issue i run into constantly. This is the problem i usually have, curved lines will create areas that have huge amounts of superfluous nodes upon expansion. My fix is to just select them all, delete them and reshape the points to redo the shape, but it gets annoying having to reshape 1 out of every 3 objects you draw after expansion because they look like the attached, it definitely muddles the fluid experience of drawing with the pencil in vector.
