I think that the idea is well-intentioned but ill-conceived. Others
have already pointed out that BRS totals the aircraft in most
deployments, usually results in injuries to the occupants, and is
otherwise very far from being a panacea.
To me the key issue and logic for BRS is: a low altitude mid-air
collision where getting out and deploying your chute is going to be
dicey at best. Like in the traffic pattern or near the pattern which
is where most collisions occur.
Best example of a BRS being worth it at low altitude:

Considering how light our gliders are--I think it's worth having--but
not mandatory.
