My point of view is that the essential ports/package functionality
should be contained in the base system in the moment the sysinstall or
make installworld finishes it's job.

I consider smooth upgrading of installed packages a part of essential
functionality.

If you're worried about the version embedded into a release being
imposed on users for next two years, well, there's always possibility to
pull a newer version of portmaster from port and install it on older
systems automatically. It has been done with pkg_install suite in the
past.

Great. I was tracking your development lately, so it's good to hear
that. I should try portmaster again soonish.

I find this a massively desirable feature to have. Defaults to on, can
be turned off. It essentially allows people to upgrade gettext to 0.16.1
and don't worry.

An acompanying utility which would try to
prune /usr/local/lib/compat/pkg, rebuilding binaries that link these old
libs, and ultimately deleting the libs, would be nice. I have something
locally, but it's a gross hack.

You understood it 100%.

Yes, that's kinda understood that anything in base must be fully
operational with only the resources available in base.
