Wait, where do you intend to parse this?
If in general I am very sceptical about this, with the load of options
that exist I see a serious chance that this will open exploitable issues
in applications that read playlists from some (non-trustworthy) remote
location and pass those directly in into ffmpeg/libavformat/...
Even if they are of the more thorough kind and do some basic validation
of the URLs they might not catch this new syntax.
