not just because of efficiency

We "need" template types at this level to be able to rid ourselves from
explicit templates (with limited layout possibilities) on the document class
definition and we need instances with names (!) there to be able to refer to
the semantic meaning to produce an explicit design by selecting an appropriate
template (ie with the right type) and instantiating it under that name

true, essentially they are only labels to "name" the instance, the same is
true for templates really. However, that shouldn't prevent us from using
sensible names to convay meaning as far as possible.
