There was some discussion of this, mostly for ARM, the general
conclusion being that sharing the code improves visibility of things for
the subsystem maintainer, ensures that the code gets reviewed (and
updated if things change) by subsystem experts and makes it more likely
that where there are things that can be shared someone will notice.
