Re: PROPOSAL: Repurpose one key and reserve it for third-party packages

IMO that would be the worst possible binding for C-z.  "Undo" is already 
bound to no less than three different keys.  Binding it to yet another key 
just to make Emacs feel closer to other editors, when all other bindings 
are so different from other editors anyway, would (IMO again) be a serious 
mistake.

Leaving just one meta key (in this case M-o) for third-party packages 
would IMO not be enough to motivate their developers to put their default 
bindings there; third-party packages should not be considered as 
second-class citizens.  It must either be a control key alone, or a 
control key and its corresponding meta key.
