Other sources of pain will include "v5 to v4" and "v5 to any v5-based
branch" porting AFAICT.

Is it really difficult to write a script that will rename most NULLs
that are safe to rename without breaking anything? Perhaps I am
forgetting some context here, but what is the primary reason why making
such a script is so difficult?
