I thought this was meant to disagree with my statement. This status message doesn't say Programmers = Big Boys, Designers = (What would you call it? little boys, girls, hobos?).
There is power in a template paradigm. Much like MVC is for people who "can't handle" hacking their entire program into a single executable, convention (guided suggestions or limitations) can do a lot for a group of developers even if they aren't collaborating with designers. If they don't recognize that, so be it (they will) but calling convention a softball for the less manly application developer is a crudely un-meditated suggestion.
