Annotations as subtitles

[JamesTheAwesomeDude]

Would it be feasible, using the lxml library, to have Youtube-DL find a way to save annotations as subtitles? (Referring mainly to its usage in MPV via the youtube-dl hook, but also for downloading: for example, downloading a video's annotations and muxing them into a WebM as WebVTT or an MKV as ASS/SSA)

I understand that this feature might be a little complicated to implement, and might require some collaboration between the authors of Youtube-DL and MPV, but it would be a very nice feature to have.

I am also requesting more support for annotations. I can download them as XML, but being able to at least see the text of them during playback would be a big help.

As someone that uses subtitles when possible already, can the text of the annotation xml file be added to the existing subtitles?

I think that part of the issue complicating this is that the annotations themselves are not a subtitle format per se, thus will require conversion, which opens up a whole new can of worms to deal with while keeping the code clean.
