If we discourage from separately installing these libraries, who will do
the required in-tree-bootstrap testing before a release on the Hosts
we care for?

Can we at least recommend using the OS vendors versions of the
libraries in case they match our minimum (not recommended) version
requirements?  Is our in-tree build support robust enough against
newer/older OS vendor installed copies?
