You're right that all those things are needed, and it did take me a while to get them all working. But now I know about tools like mail-tester [1] that analyze your emails and tell you exactly how to fix them. Once you know what to do, it's really not that much actual work to set them up.

How feasible would running a mailing list (say 10k subs, one email/week) be off your setup?

We're doing something like that.

The problem is that you need a lot more volume to be able to use the feedback loop mechanisms ( https://blog.returnpath.com/what-is-a-feedback-loop/ ) efficiently.

Sure, it all works, but it's still the old piece of shit SMTP wild wild west, because when it stops working, you can do nothing. (But usually going to the saloon, having a rough night and waiting will solve things.)
