That is all possible with ssl_var_lookup() today.  What is it you're 
trying to do that isn't possible (or efficient) today?

The API which mod_ssl exposes is the list of SSL_ variable, a list of 
(name,value) pairs.  That some of those keys are listed in the 
ssl_hook_Fixup_vars array and some are not is an implementation detail 
which makes no sense to expose in the API.

If you wanted a new API which exposes the available SSL variable *names* 
without computing the values, that might makes sense but it is expensive 
in the general case because you'd still need to parse the DNs.
