I actually think that we don't need to do anything.  We've lived for 7
years with a reality that is worse than what is now on master, and no
one complained.

But if you are very unhappy about this, we _could_ introduce a new
coding-system for *.el files.

The current behavior on master is to heed inhibit-null-byte-detection;
the current behavior in Emacs 27 is to ignore it, and always consider
a .el file with null bytes as binary.  I hope you agree that the
behavior on master is slightly better, at least in that it won't
surprise users.
