Hmm. I've pulled this, but those numbers aren't exactly "new".

They've been that way since 5.14, so what makes you think people
haven't already started depending on them?

And - once again - I want to complain about the "Link:" in that commit.

It points to a completely useless patch submission. It doesn't point
to anything useful at all.

I think it's a disease that likely comes from "b4", and people decided
that "hey, I can use the -l parameter to add that Link: field", and it
looks better that way.

And then they add it all the time, whether it makes any sense or not.

I've mainly noticed it with the -tip tree, but maybe that's just
because I've happened to look at it.

I really hate those worthless links that basically add zero actual
information to the commit.

The "Link" field is for _useful_ links. Not "let's add a link just
because we can".
