Hopefully that won't be necessary. This is a good enough fix, but we need to be
careful with the refreshes for now, so that we accidentally don't overwrite
this (more of a self-note actually :)). It would also IMO make sense to
drop the auto-generated header from the Dockerfile to help us spot a potential
overwrite during review on the next refresh.
