Not terribly; the main objection is you'd fail to update pg_shdepend.

I'm a little skeptical as to the use-case, particularly once you take
ALTER DEFAULT PRIVILEGES into account and try to figure out what that
means. If it means "apply the current default privileges", you could
easily be "resetting" to a state that never actually prevailed in the
past.
