Exemplars are good if they behave in the same way as non-core
extensions. So it might be good for the core to maintain contrib
extensions, although I would urge them to keep the size down quite
low, and to be very conservative about adding new extensions. Part of
the issue Perl ran into is that it was too liberal about adding new
stuff to core, especially modules with large dependency trees.
Anything in core should be kept very simple, both to avoid bloat and
to minimize the maintenance overhead for the core team.
