I don’t know about microscopic eukaryotes, but yes the risk is that slow-evolving life (like humans) may be wiped out.
I agree the equilibrium could be close to half mirror bacteria, though in my mind a 1:10 ratio is “close to half.” The minority chirality has various advantages. It is less vulnerable to bacteriophages (and possibly other predators). It encounters the majority chirality more frequently than the majority chirality encounters it. This means the majority chirality has very little evolutionary pressure to adapt against it, while it has lots of evolutionary pressure to adapt to the majority chirality. The minority chirality will likely produce “antimirrorics” much more, until the two sides balance out (within an environment).
It probably won’t be exactly half, because normal chirality life does start off with way more species. It might evolve better “antimirrorics” or better resistance to them. The mirror bacteria will lack the adaptions to survive in many environments, though if it evolves quickly it might survive in enough major environments to become a severe risk.
