But self-hosting email is an adventure I'm nervous to embark on.
I've been using similar aliases for years (paypal@domain.tld, ebay@domain.tld, etc), but make sure you have a contingency plan for when you're no more. I've received lots of account info from previous owners of the domain by setting up a catchall mailbox. We will obviously not care, but when someone takes over your account, they might use it to do harm to others (spam or fraud or whatever else).
Not everyone is able to say "no" to all this and still make rent next month. I'm happy the government is finally stepping in.
