I thought you've already settled on the removal of the 2-type templates
versions without '2' at the end of names, and we are speaking only about
backward compatibility. In other words, I missed the fact that
implementation based on partial specialization has its own weight in context
of writing generic code. It's really may be the most important argument,
although at the moment I can't cite any concrete example either.
