Sure, you can.

Of course, and lots of WebIDL-based specs do. These go on constructors' 
prototype objects.

Specs need to be complete with respect to function identity, since 
functions are mutable objects. The N >> 1 instance vs. prototype 
population means functions per instance is too expensive; it's easy to 

So, developers will notice if there's no prototype-based sharing. And 
implementors must know what to do.
