Comment (by reakon):

 Actually, video-only MXF would be of more help, as MXF is used in Pro
 Tools mostly for video post-production.
 Framerates supported by Pro Tools and Media Composer are: 24/1.001, 24,
 25, 30/1.001, 30, 48/1.001, 48, 50, 60/1.001, 60, 100, 120/1.001 and 120.
 That covers most of rates used by video industry, and we don't really deal
 with arbitrary non-standard rates. Therefore I don't expect any further
 tinkering to be necessary anytime soon.
