If we make 1.22 mandatory there will be no good reason to make 1.23
mandatory again. So I will have absolutely no inclination to work on
this, for example. So we are just wasting a chance to clean up the
Kbuild story w.r.t. pahole. And we are talking about just a few days
at most, while we do have a reasonable work around on the kernel side.
