Is it supported, but it's also clearly documented that people need to
enable this sysctl for custom kernels:

Why revert the kernel? That doesn't buy us anything. It would be
better to ask upstream to revisit this decision (e.g. by contacting
KSPP mailing list). I suppose that SuSE, Ubuntu and Red Hat have
are shipping similar patches/defaults, so it's probably safe to say
that those protections are now the status quo (as opposed to five
years ago when that feature was freshly introduced).
