So to be clear, you're requesting a behavior change so that expanding
${#a[0]}, ${#a[*]}, and ${#a[@]}, where a is a scalar variable, when
nounset is enabled, does not result in an unbound variable error.
Right. That is the behavior I naively expect.
Thank you for your answer.

Yeah, that makes sense. I don't mind if the change would be applied in

With nounset, ${#a[@]} for a scalar variable fails even though we can
correctly obtain the result (which is consistent with the expansion of
"${a[@]}") without nounset. This is the result with the devel
version:
$ bash -c 'a=1; echo ${#a[@]}'
