My concern with that is that indexing services come and go (and which
ones that offer indexing by message-id, which is the *only* permanent
identifier, are even more subject to change), but things that go into
the git history stays forever.  In IETF terms, the message-id is the
"resource name" (as in URN), as opposed to the "resource locator" (as in
URL).

There is of course the option of running a bounce service on kernel.org,
as long as the Message-ID is included.
