Tesla is getting closer with tendon-based hands in the next generation of Optimus. Who knows where they will end up.

Elastic tendons seem like a pretty reasonable solution to this problem, but can it be applied to all the joints (like ball-socket, etc.) I wonder?

I think the chassis of the robot should also have compliance, humans certainly do have squishy spines. I mean imagine you're on the street and you have to share sidewalk space with these things. Running into it would hurt.

The tendons are as inelastic as possible. The compliance comes from direct drive motors with no gearing (or as minimal as possible).
