Yet two-up view works fine on paper for everything while it mostly doesn't on monitors for plain text pages ... reality meets supposed reality and forces compromises.

Forcing bad outcomes for ideological purity is silly. Users will mostly be happy getting the two-up view for selected pages, if not they can use their own viewer.

That comment was against the idea of using some "viewer" that displays the underlying PDF (in the preferred manner) but does not expose the file to the end user. Like having pamphlets shown under glass, you can see but you cant take it to do what you want (standards are going this way).

PDF files can have varying page sizes (attached), if that presentation is the most important part of the content then the capability is already there. How many people actually want to print some glossy brochure with 2 page spreads but in separate split page sizes?

bw2341:
Is the Icom product brochure an example of a working PDF or a broken PDF?

I tried it in Firefox, Chrome, Edge and Adobe Acrobat Reader. All of them open in single-page view. The Icom PDF has a single cover page and two-page spreads starting with the even numbered pages. In Firefox, Edge and Adobe Acrobat Reader, I was able to change the view settings to show them properly with the cover page alone and the subsequent pages side by side. In Chrome, I could not find a setting to show the even numbered pages on the left, so in that sense, Chrome is broken.

I don't have the tools to check if the Icom PDF has Document Properties / Initial View / Page Layout set to Two-Up (Cover Page). Can you check with your tools?

If it is set correctly, it means that PDF Initial View is effectively unsupported and useless. If it isn't set, could you link to a different PDF as this one is a poor example of the problem you are trying to solve.
