This flag does not describe the mpv package, but ffmpeg instead.
It gets in the way of using finer-grained LICENSE_FLAGS in ffmpeg.
It is above all not needed, the real problem is even more clear without it:
ffmpeg was skipped: because it has a restricted license 'commercial'. Which is not whitelisted i LICENSE_FLAGS_WHITELIST
ERROR: Required build target 'mpv' has no buildable providers.
Missing or unbuildable dependency chain was: ['mpv', 'ffmpeg']
