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 Allow users invited by staff to skip approval is fixed of course…
