No, it doesn't solve all problems, but the question is whether it needs
to. We're talking about the scenario where:

a) a customer requires FIPS compliance, and
b) the customer has an app that calls getrandom() and doesn't fallback,
and
c) they're doing so with statically linked binaries or container
infrastructure that doesn't allow injection of other libraries

How common is this? Does the kernel need to solve this scenario?
