At the basic level it doesn't imply any bloat at all - if the gazetteer schema simply implements gazetteer objects as a feature-type. Thus *any* WFS software that supports an externally defined feature model (i.e. a GML application schema in which the objects of interest have content models derived from gml:AbstractFeatureType) can be used for a gazetteer server.
But I know Rob also has some other issues that he believe flow on in order to make it *useful* - and perhaps those would lead to bloat.

That would be great. Would make a nice GeoServer 1.3. I think
sponsership would definitely be in order, as putting gazetteer would
require some more refactoring. I'm currently getting a bit worried
about bloat - people who just want a nice simple wfs having
to also get
a wms, catalog, ui interface and gazetteer. I'd like to see
something
like plug-ins into a general framework, where you could choose which
components you wanted. A concept similar to the datastores
api, where
you can just include which ones you want, and easily plug in
new ones,
but extending to services. Granted I haven't thought this through
_at_all_, and may be technically super hard and not worth the
effort.
At the very least though the code base needs to be more flexible, so
that rolling a wfs only would not be too hard, perhaps
different build
targets could create different services, with their code and the
appropriate jars.Looks like it's time for me to download the gazetteer spec, as it's
something I've really never looked at. I'm excited about the
possibilities though.Chris
