That's a problem with the current approach too, no?
If I create an .el file, it's ignored -- unless
I futz with the repository too.

So this sounds like more of a 'make bootstrap'ish issue to me.
However, if it turns into a real problem in ordinary development
we can add a dependency on the lisp/** directories
as well as on the .el files.

That shouldn't be a problem.
Undumping should depend on the witness file,
not on the .el files directly; and the witness shouldn't
change unless one of the autoloads actually changed.
