Right.  I think the point that I've been trying to make is that just
like Sean: I have no gerrit server involved when I submit patches to
the list.  I do:

1. Write patch on my local machine.
2. Post v1 to mailing list.
3. Make changes.
4. Post v2 to mailing list.
5. Make changes.
5. Post v3 to mailing list.

I have never uploaded to a gerrit in this process.  THERE IS NO GERRIT
LINK!  Yet, just like Sean Paul says, I would like patchwork (or any
other system trawling through the mailing lists) to link my v1 to my
v2 to my v3.

The key here is that Change-Id needs to be consumed by machines.  Yes,
it's nice if humans can also find it useful by itself, but primarily
we need programs (like patchwork) to be able to understand it and link
v1 to v2 to v3.  Unless the link is in a super structured Canonical
form then it is WORSE for a machine to consume than just a plain
Change-Id.

Personally I'd rather keep Change-Id as-is with no link because it
means that those who already have a workflow can keep using it and
just stop stripping Change-Id.  However, if people really want a link
we can make one up.  Remember, though, that at the time of posting v1
that link points to NOWHERE.  THERE IS NO SERVER.  Thus you are
speculating that (presumably) that link will find the patch you posted
because you know that the list will be scraped by a bot.

NOTE: I suppose I could do this today:

https://lore.kernel.org/lkml/?q=Change-Id%3A+I23e218cd964f16c0b2b26127d4a5ca6529867673

...and it would work.  Ironically Mark yelled about that not providing
any use outside of the company's system, but I just effectively used
it to find v1 and v2 of the patch and also link it to what landed in
the kernel tree (where, apparently, Mark missed stripping the
Change-Id).  ...and the "discussion" about the patch.
