[Pmwiki-users] is "Main" a group, or isn't it?

It's an actual group, but you're correct that $DefaultGroup gets
handled a little strangely in that it's group configuration is loaded 
whenever the current group doesn't have a configuration file.  This
is there primarily for historical reasons.

Only because I ran into a situation where I needed to have a customization
that was executed only if no other group-level customization files were
present.

Well, the top-top level customization is performed by local/config.php,
which is applied to all groups and pages.  The loading of the 
DefaultGroup's configuration remains in PmWiki 1.0 for historical
/compatibility reasons with previous versions of PmWiki.

In PmWiki 2.0 the behavior has been changed so that $DefaultGroup's
configuration is no longer loaded, and instead a "default.php" file
is loaded if no per-group or per-page customization file was found.
