Not only parse rules, but the semantics of mapping those arguments into
the internal configuration of Apache. For example:

Options MultiViews Indexes
<Directory /foo>
  Options -Indexes
    ... line noise ...

How in the hell is the *external* processor supposed to figure out the
final value of the Options that apply inside that directory? Are you
saying the processor needs to replicate all the handling of the Options
statement? Cha, right. And monkeys are going to fly out of your butt. And
it isn't going to feel good...

We don't need a Container module. This is easily handled by the type (1)
hook that I specified in my design note. Apache provides the hook and then
does nothing else. Simple as all hell for Apache -- we declare a hook,
implement it, and run it during the file processing. What is that? Three
lines of code using those AP_HOOK macros?

Tossing the requirement for external tools just to save a few lines of
code is so backwards, it is silly.
