Don't worry, I still remember that trick of yours from this discussion:

Something like that would be a start, but I'd say having localmodconfig
covered would be wise also, as it speeds things up tremendously for
those that start with a full-blown x86 pc distro config.

There are also people that find regressions when updating from say
v5.18.15 to v5.19.4 and want to bisect that range; never tried if that
actually works with a stable git tree, but I'd assume that approach is
unwise. I also assume a lot of people would prefer to download only the
recent history or specific stable branches when cloning the git tree
(which is possible if you know what to do, but I guess most people don't).

Ciao, Thorsten
