You don't have to use the standard bridge though; I've withdrawn in less than five minutes using the Hop bridge/network, which I think just involves an additional fee to a middleman (my L1 transaction for it shows it spending ~0.02 ETH). I can't speak to what additional checks that protocol may have that would have prevented conversion of excess OETH though. Here's the FAQ for it:

Edit: O...kay? Apparently the parent of this comment is aware of alternate, much-faster ways of withdrawing L2->L1, and what their constraints are, but still elected to leave those out and imply the one-week lag was a binding constraint?

(Would have posted as a reply, but my comment rate is getting throttled for some reason.)
