Bidirectional EV charger - is it worth it?

I recently talked to someone at https://www.bidirectional.energy/ and it sounds like bi-directional charging (V2H and V2G) capability will be available for several CCS EV models in the next few months.

The benefits seem tempting but bi-directional chargers would be more expensive (probably close to $5k + installation costs?). Do y’all think it’s worth it?
