That Redditor has -5 karma. Also that idea makes pretty much zero sense when it's a matter of a couple of days to implement a simple RISC-V core from scratch.

I would not rely on that information.

It does, however, have the same external interface as Microblaze and hardware wise is a drop in replacement in existing designs.

I posted the Reddit link because it wasn't my insight - but I agree it's a dubious source. That doesn't make it wrong. (I'm not certain it's right, either - it's an interesting claim.)

A RV32I core is easy to implement from scratch, but Microblaze-V already has a single-precision FPU, and it will need an MMU to reach feature parity. It's much bigger than a weekend project to produce a RISC-V core that's feature-matched with MicroBlaze.
