My recommendation would be to match what glibc's printf does.

Right, have a new patch that does error-checking and returns a better
error on that case, update the docs to reflect that restriction, and
then (ideally as an additional and independent patch..) implement the
width capability (and, ideally, the ability to pass the width as an
argument, as glibc supports) which matches the glibc arguments.
Part of the reason that this restriction is in place, I believe, is
because glibc expects the width to come before any explicit argument
being passed and if an explicit argument is used for width then an
explicit argument has to be used for the value also, otherwise it
wouldn't be clear from the format which was the argument number and
which was the explicit width size.
I don't think it's a good idea to come up with our own format
definition, particularly one which looks so similar to the well-known
printf() format.

Agreed.
