CORE_PRIVATE may be broken from release to release, it's a necessary
concession to prevent utter stagnation :(

The bits are not CORE_PRIVATE.

You can find sample Perl code on the web that even tests these bits, though it isn't clear to me if that is a normal practice when using the Perl/mod_include interface.

I believe it was a mistake that this particular symbol/this particular
directive is not a part of the mod_includes internals :(

Perhaps, though mod_include does have a plug-in interface and we have this non-internal-detail-sounding function called ap_allow_options().  The include option variants could be interesting to such a plug-in.


So given we have a .23 mmn bump, perhaps document this in that section.
But the actual behavior of this flag changes significantly and I can't
see how to properly maintain mod_perl, deep internal compatibility.

The requirement is to fix combinations of option specifications in the main conf file and .htaccess.  There's nothing incompatible with mod_perl there.  We just can't change the meaning of existing bits.
