Big news for both the lazy homelab admin that can set a TXT once and ultimately be more secure without spraying DNS Zone Edit tokens all over their infra AND for the poor enterprise folks that have to open a ticket and wait 3 weeks for a DNS record.
It will help that side of the process (although, as a sibling has noted, you can CNAME your way into a better-controlled update service), but the challenge of automating cert changes for various non-HTTP services, including various virtual or physical boxes with funky admin interfaces, remains. I don't expect that vendors will do much about that, and it will end up on admins' plates, as usual. There will be much grumbling, but fewer solutions.
a perhaps non-obvious option is to CNAME (or NS) the `_acme_challenge` record from your main zone to another zone you can control better and can't affect production traffic the same way the main zone could. `acme-dns` is a neat little tool for exactly this, that has an https api for your ACME client to request a cert from, and a dns server to respond to dns-01 challenges from your provider.
Very true. I have been in both roles.
Why dont providers offer dns api keys restricted to txt records?
