mpv supports two hardware decoding APIs on Linux: vdpau and vaapi. Each of these has emulation wrappers. The wrappers are usually slower and have fewer features than their native opposites. In particular the libva vdpau driver is practically unmaintained. Check the vendor string and print a warning if emulation is detected. Checking vendor strings is a very stupid thing to do, but I find the thought of people using an emulated API for no reason worse. Also, make --hwdec=auto never use an API that is detected as emulated. This doesn't work quite right yet, because once one API is loaded, vo_opengl doesn't unload it, so no hardware decoding will be used if the first probed API (usually vdpau) is rejected. But good enough.
