True but it usually would suffice for installation.

I missed that. And I can't say I'm a fan. I can't think of any other instances of that kind of default...other than log path variables. Maybe that's enough precedent?

Falling back would be polite but risky. I'm fine saying this is for BundlePackage and other, well-behaved engines.
