You are adding "plug on" connections in addition to a lug. If the
connectors are good it is OK I suppose but every time you add a
connection you add a potential failure.

Same number/type of connections; just in different location...instead of
one on the breaker it's on the panel buss bar; the conventional breaker
still "plugs in"

I've yet to see one, however; wasn't aware Leviton had entered the fray
with more than just their traditional devices...

I'd have to think about it a bit, but I think Gfre is right, sounds like
there is at least one more connection and certainly they are different
type. With a regular panel a GFCI neutral would go to a screw terminal
on the neutral bar. With this panel, that connection is push on, the
breaker connects to the bar. In the grand scheme of things, I agree
with you that I don't see it as being significant though. If it's
properly designed and made, sounds like a good thing.
