I would certainly hope so- and I would expect that to go for any of the
other extensions which are included in core. If we aren't going to
maintain them and deal with security issues in them, then we should drop
them.
Which goes back to my earlier complaint that having extensions in core
which aren't or can't be marked as trusted is not a position we should
put our users in. Either they're maintained and have been vetted
through our commit process, or they aren't and should be removed.

I agree in general with dropping the unpackaged-to-XXX bits.
