One thing that makes sense is distinguishing between servers you've
defined in your gnus.el file, versus servers you've added via the
*Server* buffer in Gnus. As things are set up currently, those do need
to be held in different variables. Perhaps that might change in the
future, but this much makes sense.

What makes less sense to me is the distinction between the primary
select method and the secondary select methods. So far as I can tell,
the only practical difference between the two is that groups on the
primary select method don't have the method name prefixed to the group
name. That's something that could be profitably simplified, I think
(there's a ton of code that just checks whether the current method is
primary or secondary).

Noted! Please do let me know if you have any more ideas or responses to
that document.
