Hopefully @serverco will be able to update the code so that it knows you don’t need to pass any further challenge for that name for (approximately) 90 days.
In this case you should be able to say you’re going to pass DNS or HTTP or, I don’t know say a hypothetical custard pie race challenge, and before it even tries the challenge getssl will spot you’ve passed one already, and skip it for that name. Other names you haven’t passed any challenge for yet still need to pass a new challenge.
Done well this should “just work” although of course it’s some effort for @serverco - like a swan swimming, it looks effortless but there’s frantic work under the water.
