"pkg del -a" is a problem for use of pkg base; need a form of "pkg del --just-ports" to get rid of port packages?

"pkg del -a" includes selecting all the FreeBSD-* base packages for
deletion. Such deletion would not be appropriate.

This is an example of one area where being able to easily select to
operate on just port packages would be a good thing. Other contexts
might lead to wanting to easily select to operate just on base
packages. Some of this includes just informational outputs, such as
"pkg info -f -a" being too much output, much of it not of likely
interest because of the mix. "pkg info -f --all-base"?
"pkg info -f --all-ports"? (Just trying to suggest a general idea.)
