Sorry for borrowing you people, but is there currently a way to make ipallowlist middleware use some kind of file as a source of IPs to whitelist?

File-based allowlists are nicer when the set changes weekly.

I keep the list in git with a boring reload hook — human-readable diffs beat a long CLI flag history. Just make sure empty-file behaviour fails closed, or you’ll invent an exciting outage.
