I’ve been a Fastmail user for years, having left Gmail. It works great and have nothing be but praise for them. I use my own domain with them so if I decide to leave it’s not an issue worrying about updating people with my new email.

Do that, it's a non-issue, though I do agree with you that it shouldn't be a thing (or at least have like a multiple year embargo on the address).
I think the issue is why use an email provider that has designed such a glaring security hole into their system? Does it not raise questions about their judgment in other matters that are less visible to the user?
Second, and I don’t know how much weight this carries - but I personally know some of the people on the Fastmail team. They’re some of the most thoughtful, steady engineers I’ve ever met. Every time I’ve criticised something about Fastmail to my friends there, it turns out they’ve had the same discussion internally and immediately tell me about a bunch of arguments I hadn’t thought of which explain their final product choices. I wish much more of my software was made at companies like that. They have excellent judgement. They’re absolutely the right kind of people to host a long lived email service.
The commenter above may have never deleted the alias to release it for reuse.
Reusing email addresses is pretty universally considered terrible practice. So you may want to discuss it with your friends there.
