I don’t understand this at all for multiple reasons. Having your software or conf files reference an unchanging link is incredibly practical, I’d hardly call that “messing around with certs”. Secondly, no configurations are required to be changed - I had the client simply provide certs and then manually configured Apache and Postfix to use them.
Lastly, you’re not locked into a single client, there are multiple ones to choose from that do different things. You just need to choose the one that’s right for you. (That’s part of what I was talking about in my above post, when I said most complaints were based on misunderstandings.)
There are a small number of users that can’t use Let’s Encrypt, and StartSSL or other services may be better suited, but those cases have nothing to do with 90 day certs. You’re effectively shifting goalposts now you realise you’re in the minority.
