It would be part of the key binding conventions.  Of course nobody is 
forced to follow these conventions, nobody is fined if the don't, but 
AFAICS the vast majority of package developers do follow them.  Those who 
dislike the core Emacs development team do care about their users, and 
would not want to make their life more complicated than necessary.

As has been explained again and again, including in the post to which you 
are replying, "C-z C-z" would remain bound to "suspend-frame", all you'd 
have to do is to press three keys instead of two.  That isn't "awful", 
especially for a command you don't use once a minute.  And in case you 
personally really need "suspend-frame" on "C-z", you would of course 
always have the possibility to (global-set-key (kbd "C-z") 
'suspend-frame), and to move the keymap(s) reserved for third-party 
libraries on some other key of your choice.

A meta key alone wouldn't be an appealing solution for third-party 
developers, it must either a control key alone, or a control key and its 
corresponding meta key.
