This has been expressed before on both SourceForge and verbally on IRC/Matrix.
MIDI music playback is a feature in HeXen II. There are no other games that I know of that support MIDI in that way. In my own personal opinion, it would make sense to add it to complete support for that game and allow developers to make games utilizing MIDI music files.
This leaves the question on what the most portable approach to supporting it would be while keeping dependencies low.

I encourage outside perspectives on this matter.
