Wow, cool idea and I totally agree regarding the usefulness of this
featurewish.
sidemark: I'm kinda biased about tags, hierarchies, controlled
vocabularies, personal information management with files, ... since
these are things I do research with [1].

You do not need that many tags to provide meaningful examples that
justify this feature. Take for example following tags I am using:
location based tags:
* Graz (the city where I live)
* TUGraz (where I work)
* flat (where I actually do work too :-)
* out-of-town
* parents (not in Graz)
action based tags:
* fitness
* nonComputer
* communication
* errands
With your proposed feature I could manage to express following
dependencies:
Graz > TUGraz (TUGraz is in Graz)
Graz > flat (my flat is in Graz)
So when I create an agenda view with «Graz» I might as well see
entries which are tagged with «TUGraz» since this is a subset of
«Graz».
out-of-town | Graz (out-of-town is not in Graz)
I am not sure if this OR condition is of any use here.
out-of-town > parents (my parents are out-of-town)
Agenda views related to out-of-town should include things I have to
manage at my parents place.
nonComputer > fitness (doing sports is not computer related)
I do not count Wii games as sports :-) Agenda views related to
nonComputer stuff should also list fitness items as well.
Graz > errands (I usually buy stuff in town)
fitness ! flat (I never do actual sport in my flat)
Is there a need for explicit negation?
Looking forward to a mechanism to define (sub)sets of tags in order
to simplify queries matching tags. Because this is what I do think
it possibly means: «C-c a m +Graz|+flat» does provide the combined
sets of «Graz» and «flat» for the purpose of agenda views.
(I am not using (filtered) export yet)
