Packages in BAD_RECOMMENDATIONS don't get installed. So there's no need
for them to get removed. Do you know any real use case?

I doubt it unless proven wrong.

Actually there's only one line matching opkg-cl.*remove, which is a very
special case:

openembedded-core/meta/classes/rootfs_ipk.bbclass:
opkg-cl ${IPKG_ARGS} --force-depends remove update-rc.d base-passwd || true

P.S.: No line matches opkg-cl.*upgrade
