Does iCloud+ with custom domain support plus addressing in email addresses?

I am considering migrating from Google Workspace to iCloud+. On the email front, I have a domain and I use *"plus addressing"* in my Google managed email addresses. For example, one user account email address is joebloe@mydomain.com, and I use joebloe+tag@mydomain.com to receive emails from some services into joebloe@mydomain.com mailbox. I'm wondering if iCloud+ supports the +tag syntax for custom domains, similar to Google Workspace or Microsoft365. I've seen some people mention using iCloud+'s aliasing feature to achieve a similar result, but I have too many tags to map them all in this way. I also have a catch-all feature set up, but this would not work for me because I have multiple users on the domain using the +tag syntax and I don't want emails for janedoe+tag@mydomain.com to go to joebloe@mydomain.com - they should go to janedoe@mydomain.com instead.
