Given the single-mailbox constraint, the exposure of the address in a

the RCPT-TO envelope list (Address in To/Cc/Bcc or via a mailing list

not more than one mailbox at that domain.

I gave an admittedly-contrived example of how this could be a major issue:

MAIL FROM:<boss(_at_)example(_dot_)com>
RCPT TO:<suckers-to-be-laid-off-next-week(_at_)example(_dot_)com>
DATA
From: boss(_at_)example(_dot_)com
To: dummy(_at_)example(_dot_)com
Subject: Memo about stock-option vesting

In other words, you may not want members of an alias to know which
alias they're on.
