Adding this would be extremely helpful.

Agreed, right now finding out what the support is for Paged Media in browsers is a pain.

Current status: https://www.chromestatus.com/feature/5400251359821824 (not implemented anywhere)

PrinceXML https://www.princexml.com/ supports it. (Note: I am not affiliated with them in any way, just using their software due to the HTML/CSS print features they support that nothing else seems to).

So does Vivliostyle and probably a number of other print tools. But I don't believe caniuse tracks those.

Antenna House Formatter (https://www.antennahouse.com/antenna1/formatter/) supports GCPM as well. I would, of course, also like to see caniuse track paged media formatters alongside browsers.

Another category that should be added site-wide is EPUB/MOBI renderers (since it's all just HTML & CSS in the end). Often Amazon's documentation about what the Kindle supports is inaccurate.

CONTRIBUTING.md says it's currently not possible to add another browser.. Why's that?

I would also really like to add KF8/KFX support (see appendix 16.1+) as a common denominator for EPUB & MOBI.

I still think this is relevant today

Browser typesetting is so behind LaTeX/ConTeXt, we don't even get mention of it (6 years old exception).

+1 just came 'round looking for this for generating an Annual Directory from html to pdf and was somewhat astonished to learn it hadn't yet been implemented

Being able to use target-counter(s and target-text for online content and not just printed media would be extremely helpful.
