I happen to use a Mac, even when targeting Linux so I'd have to use a container or VM anyways. It's nice how lightweight bubblewrap would be however.

Consider one wanted to replicate the human-approval workflow that most agent harnesses offer. It's not obvious to me how that could be accomplished by dropping privileges without an escape hatch.
