It depends : it you want to keep the magic "cw" object, yes it would hurt.
But if we split cw, it would not :
self.appli -> The application, giving access to the vreg and a few
instance-related api (build_url for example).
self.cnx -> the connexion to the repo (data access, transaction
self.orm or self.dbsession -> the orm related apis, given that we
removed 'get_entity' from rset.
self.request -> the http request, for controllers
Not all appobjects would have all these attributes :
Hooks : appli & cnx
entities, sobjects and views : appli, cnx & orm
controllers : appli, cnx, orm and request
Note that I have a feeling that views should not need an access to the
request, although in many cases it can be easier to have it.
