I don't think we're off-topic. My first reply to OP was almost off-topic, because instead of curing the problem I proposed using commercial packers etc.

Returning to your list, I agree with it, with all items in it.
If root account compromised and windows admin were bad - then situation is bad enouth to even not care about few more items.

But unpacking source into filesystem is just worse than in-memory unpacks.

/tmp files are like dirt that some program forgot to clean after its run
As another example, 'perldoc' also a dirty program on Windows, and I wish it change its behaviour, but I have no resources to change this.

The situation is very similar to a vacuum-cleaner engine that is noisy and makes dust due to large air flows.
You explain that it is dirty and noisy enough already all around so we can agree additional noice and dust almost un-noticeable. Bur I still prefer silent and clean vacuum-cleaner.

I have very deep respect on PAR, and its author, and maintainers, and for you personally, you all do great job on providing simple solution, which makes commercial packagers to live harder - and this is a good thing.
But looking at situation differently - there is a better approach, which PAR can not do (due to some technical reasons you just said)

With really large regards,
Vadim
