It's a bit silly to wait for a completely different radio transport before thinking of carrier and backhaul improvements, which are almost completely orthogonal.

Given the specifics of the sorts of flaws in these network standards, it's hard to come away feeling that they were anything short of intentional. I get the impression that “working on it” more or less amounts to improving plausible deniability by making the backdoors less obvious.

Development on radio access and core network does indeed happen in parallel, and as far as I know, the core network overhaul was not delayed to wait for the radio-layer.
But marketing-wise, the radio-layer is what makes the phone show a 5G icon.
As far as I remember, there will be some sort of "layered" encryption. The innermost layer is the user's payload, end-to-end encrypted between operators. Each service provider (responsible for transporting the data) adds patches with modifications and a signature by the service provider.
Not sure if that actually made it into the standard yet. I think the motivation is that roaming requires cost-effective routing, fraud detection,.. so there's a whole business ecosystem around that.
Long story short: I think people are working on this
