But steel's more ductile, so basalt-reinforcement failures are less gradual, providing less margin of safety or ability to patch repair (all things being equal). It's more similar to glass reinforcement (both available in bars, mats, and fibers), which is seeing increased use, but better than glass.

Good point. I've heard similar complaints about engineered wood (glulam and friends) for structures vs regular lumber. In fires, solid lumber fails gradually and makes lots of noises before it does, whereas engineered wood just goes BANG and fails at some point.

I don't think this stops these new products from being used, it's just another engineering tradeoff.
