The footer on each message is rather annoying, mostly because it breaks
digital signatures. Should it be set to the empty string, or do its
benefits outweigh the drawbacks?
Looks like Google mangles the message in other ways, too. In my case,
the charset is changed from us-ascii to UTF-8, and the
Content-Transfer-Encoding header is removed, with the `=20` at the end
of one line being replaced by a space. So the only solutions are either
inline PGP or to switch list hosting solutions.

As far as I can tell from examining the settings interface, it can't be entirely removed or entirely replaced with an empty string. Google Groups will not allow it.
And to be honest, I think some kind of automatic footer with basic ML
info is a good thing. I am on a few ML that don't have it, and every now
and then somebody sends an email _to the list_ asking how to
unsubscribe...
Having a link to the message in the footer is also convenient sometimes.
Google used to put the footer in a separate mime part, which was
compatible with signatures, but they changed it. I have no idea what
other (non-self-hosted) providers do.

Why did Google make this change? Has anyone complained to them about
it?

Doesn't it also break DMARC? I remember that was a big fight 5 or so
years ago to get all of the mailing list software to do something that
was compatible with DMARC because all messages that came through
mailling lists from a source that enabled DMARC to a MTA that enforced
DMARC were bouncing.

I wouldn't care that much about the footer if the content is kept intact, but I think some mailing list software also messes up with multipart MIME messages. Haven't seen that here, but on mailman lists...

Use ‘p’ to select the PGP menu, then select “inline format” and “sign”.

I suspect Google Groups deals with the problem by mangling the `From:`
header where necessary. That reminds me: Marek, should Qubes OS have
p=reject?
