I can think of a number of reasons not to support it.

In any case, feel free to submit a patch; you may even be able to
borrow some of the code from bash's printf.

You can find instructions for contributing code to gawk at
https://www.gnu.org/software/gawk/manual/html_node/Additions.html#Additions.

Along with code changes, please include updates to the Texinfo manual
and to the troff man page, as well as at least one additional program
for the test suite.

Thanks!
