Please revert this (the removal of .config).
I got some strange reports that our external module install broke, and
traced it to this change. Our external module references the .config
because we have different logic for the build depending on if other, related
modules are present or not.
Also, it looks like this broke DKMS for some configurations, which not only
impacts DKMS itself [1] but also downstream projects [2].
While DKMS may be updated going forward to avoid this issue, there are
plenty of affected version out in the wild.
Also, I haven't surveyed every distro, but it looks like Ubuntu still
packages the .config with their headers in their upcoming "Plucky" release
based on 6.12. I suspect they wouldn't do that if they didn't feel it was
needed/useful.

Hi Jeff,
do you know the related thread [1]? According to the last mail, DKMS
has fixed its issue already in December.
DKMS tip might be fixed, but production versions are in various distros,
which are not updated. Therefore actual users are impacted by this.
What happened to the #1 rule of kernel, that we do not break users?
This still needs to be reverted.

Kind regards,
Nicolas
