Huh? It's not intended to be aggressive.

Well, at least from my POV it's making some packages need host-pkgconf
just because they use gtk-doc.m4, we're bumping the version and they're
AUTORECONFed. If they weren't AUTORECONFed they maybe didn't need
host-pkgconf (maybe for other purposes, but not because of the old
gtk-doc.m4) so it seems to me it's autotools/autoreconfs fault, and it
should be handled there.
It has nothing to do with packages that don't account for host-pkgconf
usage without accounting for it in the first place.
Regards.
