You're not the first one with this idea. It's inevitable that this will
happen at some time. But, as was expressed in some other place of this
thread this needs some effort before it's done. It's going to break a
big part of distribution (far more than 3.6%) if it's done now, and
would need serious effort to be done.

So, why not create a wiki page, plan how to make this harm the least it
can (limit the number of packages affected by calling for changes before
the rule is enforced), and get it through packaging commitee (or
fesco?).
