Thanks, I would have to agree here :)

Most excellent, didn't know that part.  Ping we off-list if you're interested
in automating this, I also use these containers (or sometimes extensions with
additional build-dependencies) to test builds in CI settings. Setting that
can be pretty straightforward and self-contained.  It's easiest to instrument
when you don't even need other build dependencies.
