First of all, the capifs story is orthogonal to the major claim.

But basically you are right, capifs is likely not needed anymore. The
only user visible change - and that was holding me back to suggest its
removal - is the time when the NCCI minor ttys show up under /dev/capi/
(or wherever you direct them to). If I didn't miss something about udev,
it will make all possible minors pop up once the major is registered.
However, I'm not sure if there is some userland actually relying on this.
