I am not so worried about security... I brought the point here because
this is the packaging and distribution list, and I see this as an
emerging pattern for the packaging and distribution of bootstrap
scripts and this is something that has not been discussed much before.

Conceptually I find these no different from setup.py scripts, and
these have been mostly normalized (or at the minimum have a
conventional name and a conventional if not specified interface.)

Yet today, for the all important core package and environment
management tools, we have bootstrap scripts each with different
interfaces and different approaches to self containment or no

I feel this is worth discussing as bootstrapping is where everything begins :)
