For what purpose?

I'm not sure we want yet another config debug option. These are all expert
level configuration and honestly I would rather such users _think_ about
what options they are enabling instead of giving them a large hammer.

If enough load, this can also make boxes completely locked up for any sort of
testing/debugging. I vote no.

Also, CI efforts such 0-day already have the necessary scripting to cover the
debug options that make sense.

Thanks,
