This is planned to implementation in rsbac version 1.5.

I think it could be safer to make learning mode to automatic generate roles
and types in software that are in /sbin /usr/sbin that use IPC as /sbin/init
could be or daemons as ssh. With this novice users that don't know that it
should be isolated it could be at least a bit safer.

I'm not so sure in binaries that are under /usr/bin in particular (with the
Xorg exception) such as firefox since I don't see with good eyes that every
user share the same rol in navigation being needed a role transition between
firefox_r and user_r to avoid that root for example could navigate through
users directories and being at least a more properly solution a simply jail
for example that RC, in these cases a further restriction could be needed
(at least CAP_DAC_READ_SEARCH DAC_OVERRIDE revoked).
