I'm not sure why avoiding arbitrary code execution during install is important when you're going to do arbitrary code execution shortly after. What else is the purpose of installing a package?

You have just ignored the point that your parent point was making. It's not the install case that they were complaining about.

True. It's surprising to optimize for such a rare kind of user.

trying to not run arbitrary code on the enterprise network is prudent.

But that'd happen anyway when the installed package gets executed.
