Exactly, removing unnecessary features is one of the nicest features we
can add IMO!

We were trying to stick to technical issues and leave all the "support"
issues to higher-ups, but support is clearly part of it.  This came up
because we do not want to support these other services in any official
way, I've been told.  So, the step of not loading these services is a
first, small, necessary step toward not supporting them.  Next, others can
sort out whether a product should leave out the services, or include with
caveats, or something else...

I'm not passionately in favor of either way either, I was just trying to
help sort our the technical steps involved in unsupporting them.
