Most people don't do that anyway, so no big loss. Don't they? People put email addresses on business cards and billboards and things like that. That's where you would need people to upgrade -- the fix would be to use QR codes but then you need everybody to support that (and understand what to do with it). Of course, people who have their own domains have long been doing something similar but with human readable names. You have example.com so you can create foo@example.com, bar@example.com, a hundred names for a hundred services. It would also be possible to do this with subdomains. So if you were bob@gmail.com, gmail could theoretically let you create aliases like foo@bob.gmail.com and use it for your business with Foo Corp. They do let you do something similar by ignoring dots in the address, so john.smith@gmail.com is automatically an alias for johnsmith@gmail.com, but if you use dots in different places for different activities then when one of them starts getting spammed you discontinue it and add a rule to trash everything sent to that alias. The inconvenience there is it's harder to remember what you used each variation for (and which ones you've already used) when it's time to rotate.
