Ahh yes the: we can’t have self signed certificates for security reasons but also can’t open up the environment to the web, and we dont have our own CA server, trifecta.
Solution: awkward, manual, certificate import process from a 3rd party vendor.
Even if you have an internal CA, few appliances support this kind of automation. At best, they have an API, and you get to write that automation yourself for each appliance.
Knew a place where, for some devices, it was only available via a web interface. It was automated via WebDriver by a sysadmin that was losing his mind.
I’m sorry, but has no-one heard of https://letsencrypt.org that issues certificates via API for free?
I would not be surprised if certificates at some point will be issued for each session.
I’m sorry, but have you ever needed to manage some certificates for a legacy system or something that isn’t just a simple public facing webserver?
Automation becomes complicated very quickly. And you don’t want to give DNS mutation access to all those systems to renew with DNS-01.

You can delegate to isolated nameservers with DNS-01, there’s no need to have control over the primary zone: https://www.eff.org/deeplinks/2018/02/technical-deep-dive-securing-automation-acme-dns-challenge-validation
Yes, and that is where we enter the complicated territories…
How complicated is it to have a CNAME? /s
