[ Sorry, `debbugs.gnu.org` appears to be down, so I couldn't read the
whole bug report, so I haven't seen the patch among other things.
Hopefully that doesn't invalidate my comment :-) ]

AFAICT `save-some-buffers-functions` is brand new in Emacs-29.1 and
currently gets called sometimes with 1 and sometimes with 2 arguments
(that's a somewhat unusual API in this respect), so it's probably OK to
break backward compatibility because it will only affect fresh code that
can easily be adjusted.
[ Arguably, it would be even better to arrange for `hyperdrive.el` to
save its buffers "in the usual way", i.e. relying on
`buffer-offer-save`, `save-buffer`, `buffer-save-without-query, ... ]
