And if it can, I feel the most users for this would be email harvesting spam bots. Which would not be super nice. Although in ideal and less common scenarios it could actually be useful for IR purposes.
I use anti spam addresses to register to new services.
I typically use throw away email addresses instead since they're free. If I actually want to use the service/account some day I'll sign up properly.
I expect someday the primary email providers will generate aliases on demand.
The example above is about giving a direct line to be contacted through email on a personal site or blog, heck even a professional one.

I know at least ProtonMail does it. But also theres the email#tag@gmail.com trick that works nicely enough.
It's not a literal alias, but it works out fine.
One of these days I'm going to propose the Thunderbird + K-9 mail addons that say 'set the sent from email address to be equal to the sent to email address', that way if service@myusername.fastmail.com is the recipient, it will be the sender to any replies, rather than the MUA default replying with myusername@fastmail.com (but that's a separate discussion)
I guess its because they do want legitimate people to reach them easily (students, collaborators etc) and if spams do go through — well they'd probably ignore it, just like they ignore other emails.
(More likely to be useful than Outlook's typically wildly incorrect guesses at when someone's suggesting a meeting/calendar event!)
