That's another solution indeed, but IMO it is not a reasonable one.  It is 
reasonable for a package to create global bindings, to write its 
documentation with these bindings, and for users to install the package 
and to access it through these bindings without having to set specific 
configuration options beforehand.  It is IMO not reasonable to require 
from all users to add "global-set-key"s in their configuration before 
using a package.

That's a similar, but different problem: it's a conflict between package X 
and package Y, not a conflict between package X and Emacs.  Moreover the 
likelihood that two packages use the same keys is much lower when many 
keys are available.
