In my case, this prevented a fallback to an old builtin MPL2 subtitle
parser to fail. I can also see other things that are stored in text
files and which the application might want to handle itself, like
playlists.

On the other hand, I see no reasonable argument why libavcodec
should render text files as video. There are much better ways to view
text files.

It might be bad for various video processing tools as well if random
text files are detected as video.
