[Pmwiki-users] Hierarchical Groups?

[Konstantin]

Hello,
If I'm not mistaken, PmWiki doesn't currently allow to structure Groups
hierarchically. That is, it is not possible to create a group like
Some.Interesting.Group
So I was wondering, why aren't such "hierarchical" groups implemented in
PmWiki? It seems (to me now) that implementation would be more-or-less
trivial (it is seems to be sufficient to allow the dots or / in group names
and perhaps add some special handling for the case of uploads).
Such organization of groups would allow to structure Wiki pages better.

Are there are some conceptual reasons for not implementing such a feature
that I have overlooked?

Konstantin.
