No, this is not contrary to POSIX. I explain it in the ticket you cited.

No, we won't do that. Gnulib is meant to make GNU and POSIX compatible
behaviour available to applications on all platforms. The requested
behaviour, which amounts to adding //TRANSLIT implicitly to *all*
iconv conversions, would be a degradation compared to what we have in
glibc and GNU libiconv.

It won't help you, since it implements the same behaviour: strict
conversion checking when //TRANSLIT or //IGNORE is not specified, and
loose conversion when //TRANSLIT is specified.
