   If developers are forbidden from manually altering the output of a
   compiled grammar, that is a usage restriction.

The problem is that the differences aren't accountable, not that there are
differences.  To be accountable, the path from original to current must be
transparent.  If that path involves manual editing, a commit (+ ChangeLog)
should be generated.  If that path is machine manifested, the program that
does the change must be distributed (+ commit + ChangeLog, of course).  In
the case of distribution, GPL comes into play (recursively).
