Sorry, of course you din't realize that sharing interface files had
this consequence, otherwise you'd have protested beforehand.

The problem is that this consequence seems unavoidable: if two
policies have different numbers to convey, through a shared interface
file, then they must be allowed to write their different numbers. To
me, this doesn't sound like a problem.

The only other natural option is no unification, unless you have a
third way.

What do you prefer, or propose?
