I think that workaround predated the switch to nanobind by a long time, and I've but tracked the evolution recently. 

Iirc, this exception was showing up in hot paths of Jax IR processing. But that was many years ago and I don't have any access/insights beyond that. I think the original performance issue was reported by @hawkinsp 

I have no objection to modernizing this.
