The problem is if someone figures it out and starts sending you spam to {random}@domain.tld. That's when you will need to sit down and start creating actual aliases for all those used email addresses and stop the catch-all forwarding:)
Also, another downside is that you will loose privacy by using your own domain.
And the lack of privacy makes targeted scam/phishing more likely, and targeted scam is the one we are most susceptible to.
All in all, I am not saying this is bad idea, in fact I am doing it myself, just pointing out this is not so black and white.
Using iCloud solves those problems, but puts you at risk of getting your account banned and loosing access to those emails, so there is that.
Probably best way to deal with it is to get dedicated email domain with a bunch of your friends, and hook it up with something like SimpleLogin. But that's gets complicated quickly ;)
