All these discussions are in the context of v7, no doubts.

I'm also thinking that probably this approach doesn't help with the case 
which
is bothering us most, where we don't have *tag* classes, but function 
objects...

However, I like that idea: it appears to reduce the overall number of 
templates
and simplify the implementation, at least. Don't you agree?
