*Anything* can be implemented as a macro... ;-)

SSLPolicy does *not* mean: "compression off, protocols x y z, ciphers 
SSLPolicy means: "what your Apache provider considers best SSL settings for 
modern browsers"

If you build from source from httpd.apache.org, it is what Mozilla considers 
at the time of our release. If you get it from a distro, it means what they 
think relevant.
They could update it in years to come for an Apache in their LTS line.

By doing it as a new directive, we enable good advice:

"If you have an Apache > 2.4.30, use the following to configure your https: 

Instead of:

"If you have an Apache > 2.4.30 with the standard macro definitions included 
and mod_macro
enabled, use the following... Btw. do not edit the macro definitions or your 
settings will
no longer auto-update. But if you do, check after every update also, if the 
macros are still
as you want them, because your changes may also have been overwritten."

The macro approach will not work for an internet that will be 99% https: very, 
very soon, IMO.
