If you use this approach, once 10 of your aliases are in the HIBP database you will need to pay for a subscription to see breaches for your domain (and even then the $40/year tier is only good for 25 aliases).
I wish HIBP had a solution for those of us who are individuals but use a domain catchall to manage online accounts.
