Why the rush?

Not really. I want it tested for a while so that we can see it in some real situations and determine whether this is a good idea at all. Or simply to make more people aware of the idea before suddenly converting everything at once and making it a fait accompli much to their dismay. Like we did with {{label}}, with, as I think, some success.

Well there's nothing preventing you from creating a separate template, {{m2}} or the like, and experiment with it.
