I think you got this paragraph mangled?

Anyway, your reasoning is spurious. There *is* no useful way to update
Perl besides pkg_rr or similar without setting up a whole extra pkgsrc
installation to do bulk builds in.

(Because every package with a perl script depends on perl, and this
includes a number of foundational packages like glib2, if you make
update you can easily spend the whole day compiling, even though all
that really needs to be rebuilt are the perl modules. Such lengths of
downtime are not acceptable in many/most contexts.)

No amount of DESTDIR handling or pointlessly littering one's pkgsrc
tree with leftover binary packages is going to change this basic
proposition.

I know you think bulk builds are the answer to every problem; however,
most people don't want to go to that trouble. It seems like you're
working toward a world where everyone either has to use prebuilt
binary packages or set up their own pbulk apparatus, and I think that
would be a serious mistake.
