They absolutely are. NSA is obsessed with post-quantum projects atm

  But is this because they are already needed or because they want to preserve encryption for past and present data post-quantum?

    The latter

  tbh they could just be pushing for people to adopt newer, less-tested, weaker algorithms. switch from something battle-hardened to the QuantResist2000 algorithm which they've figured out how to break with lattice reduction and a couple of GPUs like those minecraft guys did.

    Hybrid approaches are at least as strong as their strongest algorithm. You don't need to trust me on this, it's extremely simple to derive this principle yourself from basic knowledge of cryptography.
