If you mean .el files without a cookie, then definitely yes.

Not sure how you would detect that.
Ideally we should try to find a way to recompile code (and emit warnings) 
without inconveniencing the user too much.

If we had a modest pot of money, we could sponsor young and coming (or old and 
going) programmers for converting code using dynamic binding that is still in 
regular use.
