So far I understand, the pppd capiplugin is the only user of it, so it could
be disabled for most users without any problems, as long they are not using
PPP connections via CAPI.

I never understand capifs very well, I think that it can be dropped because of
udev, but maybe need some adjustment in user space as well (make sure that
udev did create the node before open it).

I f I remember correctly, here was some proposal to replace the /dev/capi/
nodes with devpts, this would remove the complete capi_tty device major
as well.
