Sorry, what do you mean by "conflicts"? I mean that there's countless
code today that uses "int s = foo.size()" (or indexOf, or similar); such
code will now trigger narrowing warnings.

The chance that non-generic code uses this is practically 0 and we know
it. Yes, "auto" will work, but still has anyone actually did the
exercise on a big codebase (Creator, KDE, ...) and checked how many
warnings are we talking about?
