The other change, that has has some discussion, is to make WRKDIR be
work-$PKGNAME or something like that, for all packages that have
versions.

It is an interesting suggestion to have the dependency call be "make
package-install clean" instead of just "make package-install".  We have
generally avoided implicit cleans, but I'm not sure that's helpful on
balance.

No need; the problems are understood in theory :-)

Most people just nuke all the work dirs and build again, and then it
works.  If you have something where

loop:
  make package-install
  # observe failure
  rm -rf /usr/pkgsrc/*/*/work
  goto loop

doesn't converge pretty quickly, that's much more interesting.
