Sort of.  The concept of things tuning themselves automatically makes
a lot of sense.

I'm not at all certain about tunables being exported just to be hidden
again.  Ideally you don't even want the fact that these things are
varying visible to the user.

So I think that if you can find a good example that cannot be solved
better another way, you can build a case for your framework.
Currently I am doubt you can find such a case.

At a quick glance max_threads and max_files appear even more to be
DOS limits and not tunables and even less applicable to needing any
tuning at all.  My gut feel is at worst these values may need a little
better boot time defaults but otherwise they the should be good.
