package-autoload-ensure-default-file now uses autoload-rubric internally
and no longer contains the line quoted above with "no-byte-compile".
However, autoload-rubric still contains it.

I guess the question is if it's there for good reason or could perhaps
be omitted.  If there's a good reason for it, perhaps this bug should be
closed as wontfix.

Noam, I noted that you added a comment to this particular line recently
in commit 1f7b602f84.  Could you perhaps shed some light on why we use
no-byte-compile here?

Thanks,
