I've always disliked IT discussions for reasons like this. Everyone who comments seems to think that the mitigations, security considerations, and security compromises (IE, not caring if your images are leaked online) they've made are common knowledge... But, this is a forum advising people on how to configure their home severs for hobbiest use. Best practices should be the mantra, "just raw dog ssh on the internet with your 443/80 port mapping and you're g2g" [sic] shouldn't be an acceptable answer to you. If they'd stated that there are security considerations, but they like to implement them and expose ssh to the net for management purposes I'd have nothing to say, but to just advise people who lack that extra experience, without helping them understand why you're okay doing what you're doing and what you've done to solve for specific issues that the default configuration does not seems unhelpful at best.
