That concern applies to URL's. Red Hat could get shut down by IBM, at
which point all of the links to bugzilla.redhat.com could go away.
Yeah, unlikely, but so is chromium.gerrit.com going away. We never
requested a commitment from Red Hat that bugzilla.redhat.com would go
away before we allowed Red Hat bugzilla links in git descriptions.
Ditto for launchpad.net, etc. In fact, I'd argue that launchpad is
even more likely to disappear given that it's all subject to the whims
of Mark Shuttleworth. :-)

Ditto links to patchwork.freedesktop.org, patchwork.ozlabs.org, etc.

Surely it's obvious that:

Link: https://linux-review.googlesource.com/c/1158

is more useful than:

Change-Id: I3268f9036512c4378cde1da37e0612b43ed4d384

And given that we're not disallowing other Link: trailers, it seems to
be purely an anti-Gerrit bias which is causing people to say, "Nein!"
for links into Gerrit servers as opposed to Bugzilla or Patchwork
servers.
