There is the reviewable claiming admin setting too, but it doesn’t appear to apply to approving users currently. If it did that would be almost perfect.

Totally agree! It would be massively helpful to have this also apply to sign-up requests.

For us, it would only be useful once New users need approval despite being invited is fixed of course…
