The command line "--allowAnything" in general is meant to be an
escape hatch for unusual situations, and if a workflow requires
constant use of that escape hatch, there is something wrong either
in the workflow or in the tool used in the workflow, and it is what
we should first see if we can fix, I would think, before making it
easy to constantly use the escape hatch.

I didn't look at the external reference you looked at but it sounds
like your review comment is taking the topic in the right direction.

Thanks for digging for the backstory.
