These same containers are also available for use outside of CI, eg.
with 'make ci-build', so I think we should keep building them.

As for slowing down builds, that still only applies to the first
build after Dockerfiles are updated, so I don't think it ultimately
matters very much.

Okay, even though as we discussed separately the whole idea of
splitting jobs between regular and extra might be more trouble than
it's worth and be more confusing than helpful.
