No, because then we'd be stuck supporting every piece of code 
that used to compile, whether or not it was ever legal code. 
Illegal code that compiles is a bug; bugs must be fixed.

There are some changes that could be handled in the way you 
describe, e.g. the -dip25 flag. Doing more of these risks getting 
in to complicated interactions between them.

It's a reasonable request, but it's not going to happen except in 
carefully limited cases.
