Yes. Although we are studying CSSPO, which uses a mixed (LBR + software-sampled stacks) approach.

I'm familiar with the paper, but it doesn't improve the situation in terms of LBR availability on cloud providers, does it?

Yes, existing limitations apply. Without hardware LBR support, we cannot provide sPGO profiles. However, the basic profiling should work fine.
