I wouldn't be interested in it, because
- The complexity cost is high: We already have 15 *printf-posix modules.
We would need to add 15 additional *printf-gnu modules.
Add then we would need to add support for it to xgettext's format string
parser, and add a way to tell xgettext to distinguish "c-format" and
"c-gnu-format" strings...
- It is a limited and ad-hoc extension of *printf. It is not useful for
printing application-defined error strings, nor native Windows
GetLastError() error strings.

That's what I would go for, yes.
