Hey,
VDPAU is being used on my R9-280X with the open source driver, but it doesn't support h.264's extended or advanced high profiles so far. Furthermore, the maximum supported video width is 2048. This seems to comply with feature set C.
Is there any chance to gain support for the aforementioned profiles and/or even higher widths?

VDPAU feature sets are specific to Nvidia hardware, they're irrelevant for your Radeon.
The constrained and *_high profiles are subsets of the regular baseline/main/high profiles, the hardware can play them, it's just a cosmetic issue that vdpauinfo lists them as seemingly unsupported, but there won't be issues playing them. HIGH_444 is different, that one requires special support, but the chance that you'll encounter high_444 videos is really low (if it gets used, then in intermediate stages of video production, not as an end-user format). Then there's extended, nothing uses that, you will not encounter extended profile videos ever.
No idea about video size, whether that's an artificial driver limitation that can easily be changed, or a hardware limitation. I'd say the only place where you'll be able to get an answer is the mesa mailing list.
Basically, the only thing you need to concern yourself with is video size, but even that only if you intend to watch 4K video.

Thanks for the clarification! I'm actually playing videos in 1440p solution quite frequently, so hardware acceleration would be nice to have. Anyway, I may check the mailing list then.
