That's not clear to me; do you mean that the old version is removed
first, as in make replace, or just that the new version is installed, as
if you had done "rm -rf /var/db/pkg/oldpkg-x.y" first?

It's only one command per package that should already have been updated
but hasn't, but I see your point.

It should be possible to make a "package-install-or-replace" target that
builds a package and either does package-install, if not installed or
replace, if installed, and use that as DEPENDS_TARGET.  That of course
trades one problem for another, but it's a reasonable thing to do, given
that you are in an unsound situation to start with.

Yes.  In theory, those depend on osabi, and if not probably there's a
bug, but in  general if something is trouble, you need to update it.

If you don't like the process of noticing trouble and dealing with it,
you should stick to release branches of netbsd and of pkgsrc.

Even without that, pkgsrc has updates to packages and if you haven't
reinstalled them, they are then no longer matching.

My advice is not to do that.  After you update the pkgsrc tree
(globally), run pkg_rr and fix any problems.

Usually, the amount of manual work is fairly small, compared to the
total packages affected.

Perhaps; see the pkgsrc tree, the wiki, and various guides on the web.

That's also unsound; packages have prefix baked in.   You could
re-bootstrap as /usr/pkg1 /usr/pkg2 and so on.

What I do is run pkg_rr with -k, rm all my workdirs, update, repeat,
until I get to a fixed set of failing packages.  I then rm packages if
the problem is that they build but don't install, noting what to
rebuild.  And packages that don't build, I fix (or complain about!).

You are of course welcome to do as you choose.  But it is not a
reasonable expectation that tracking pkgsrc-current will be free of
