Sadly, the point is that EXPERIMENTAL is enabled in all distros and by
most users, so you *could* flag your feature CONFIG_EXPERIMENTAL, but
the only thing taht might accomplish is making you feel ok to be less
careful.

Of course, an alternative to this patch would be a purging - pull
the CONFIG_EXPERIMENTAL tag from all options which anyone might be
wanting to use by default. Then let CONFIG_EXPERIMENTAL serve its
original purpose.
