Ah, thanks for that hint: Git commit be6cca78 indicates that the wiki 
edit was deliberate, and that their position indeed have changed: It has 
shrunk from a wide range of issues to only concretely mention subtitles.

Same README.md also (slightly above your quote) indicates their giving 
up on long-term maintainability due to FFmpeg (likely implying Libav too 
- my point here is not to throw mud):

Ok, so exotic subtitle formats is a "particular" reason for mpv authors 
to favor FFmpeg over libav.

I personally use mpv almost daily, with material from many different 
sources.  I am not a native english speaker so appreciate material with 
subtitles and sometimes fetch it myself, and would notice material 
including subtitles but failing to work.  Nevertheless I do not recall 
subtitles ever failing to work.  No doubt subtitles exist in weird 
formats somewhere, but my point is that personally I have not needed any 
of those more exotic subtitle formats.

How many of you can honestly say that you suffer from inferior subtitle 
support in mpv in Debian (i.e. the package linked against libav)?

How many of you use the mpv in experimental - and if so, which concrete 
features was lacking from the package in unstable that made you do so?
