Can we get stronger Kconfig text indicating that this shouldn't be
turned on lightly? I'll be turning the option off in Fedora but sending
out reports from what was found.

It hides behind CONFIG_DEBUG already. Is there a better option that
distros won't turn on?

For Fedora rawhide, we tend to turn on debug options that don't have
a significant performance impact to hopefully make the kernel better
for Fedora stable releases. Apart from a more explicit Kconfig text,
you could hide it behind CONFIG_EXPERT which Fedora doesn't turn on
and is more of a hint that this should only be used in specific
