This ensures that, when changes are made to these scripts, the files that
are generated from them are re-generated.
Historically this probably was not noticed because (a) they seldom changed
and (b) we had a small team and I told people to re-run bootstrapping
scripts or clean files. The team is much larger now, and regardless,
there's no reason not to have had this in place.
