Hmm... there's still a slight problem here: this can't properly 
differentiate between
   Class.SubClass.SomePage
and
   Class.Sub.Class.SomePage

I think the root of this problem is that using wildcards in group names 
is that group names then contain both structural and terminological 
information; I'm pretty sure that this will spawn other problems in time.

'fmt=hierarchy' essentially would have to check what previous group 
names are a prefix of the current group name, and to infer how deeply 
indented the current group name would have to be.

Apart from my unease with mixing structure and terminology in group 
names, yes.

Not for sibling pages, but there *should* be a serious overhead for 
child pages.
