I agree this makes sense for the general case, but I wanted to point out
that requiring a plugin for the simple cases is significantly harder for
users than some in-source extension mechanism.
E.g., firefox has a logging printf that accepts "%hs" to print char16_t*
strings. This extension means that printf checking can't be used here.
Requiring a plugin to deal with this situation would also be difficult.
However letting one write __attribute__((printf, 1, 2, "hs", char16_t*))
would solve this nicely.
I suppose I think that a format-for-a-specific-type is the most common
kind of extension and so may deserve special treatment.
