IMHO, the idea of a decent set of common, shared, english-named, standard templates is really a a good one. Noone have nothing against the fact that reserved words of any programming language is english-named and standard.
I presume, that many of existing templates aren't used into ns0 or other content namespaces; in my opinion, the core shared templates should be focused on common content namespaces troubles.
Please consider too that many templates require some peculiar css settings too; perhaps a common, shared ccs for tags used in content namespaces would be both more simple to do, and very useful so build a shared group of templates.
