What is the recommended way of dealing with the base versions of
commands when installing a package version instead? Should I chmod -x
the base executable(s), delete them or rename them? What happens if I
subsequently do a freebsd-update - do the base executables get
reinstated or are they ignored?

The specific case I'm interested in is unbound under 11.2, but this
applies to a variety of programs (CUPS vs base lpr, or base vs pkg llvm
come to mind) and if there's any official guidance on this I've missed it.
