The enable-load-all-modules behavior was what the build always did
before 2.4. That was a big annoyance and it was decided to no longer
load all build modules by default starting with 2.4. So the maintainer
mode behaves as for versions before 2.4 w.r.t. loading modules but no
longer behaves like the normal mode for 2.4.

Modules not working on a platform should not get build, this would be a
bug but has not been observed yet. The enable-load-all-modules only
means *if* a modules is build, then activate the LoadModule directive in
Whether a module is build or not is decided based on the m4 macros that
test its dependencies etc. I'd say concerning your original mail, the
possible bug is in ssl, i.e. should --without-ssl imply --disable-ssl.
I ran three builds on my (Solaris) system with configure flags close to
yours, one without maintainer mode, one with it and one with it but
--disable-load-all-modules. In all three cases 78 modules get build
(including mod_ssl). Without maintainer mode or with maintainer mode but
--disable-load-all-modules of these 78 only 21 get loaded by default (no
proxy, no ssl):
