:-) Yeah, lkml.org is bad.

That said, I prefer the lkml.kernel.org/r/ variant over
lore.kernel.org/lkml/ in part because it existed first and I'm lazy, in
part because it's shorter and in part because lkml.kernel.org/r/ is an
explicit redirect and lore is 'just' an archive it can redirect to
(although admittedly, it looks rather unlikely lore is going to die).

I'll not make a big point of it though and will in all likelyhood accept
lore links. The important point is that it has the MessageID in.
