One could argue (although I personally will not necessarily agree)
that making sure site-lisp loads fine _is_ part of the sanity check,
since a failure to load that is not necessarily due to problem in
site-lisp, it could be a problem with the built Emacs.

Thanks, but I don't think it's trivial, so please install it on
master, as I don't want any changes in the build at this late stage of
Emacs 29 release cycle.

Also, please use -Q, not --quick, as I think the former is more
familiar.
