Bid cancellations considered harmful

Is it viable for relays to implement logical clock logic to effectively hold a proposer accountable to committing to their final getHeader bid? Relay here will check scalar value of clock against that of header to ensure to corresponds, or would such lead to grievances to proposer made ny builders trying to underbid leading up to whenever a proposer sends their final getHeader request to relay?

I think it’s not really needed. The relay can just offer better builder cancellations as a service if they want to (Relays in a post-ePBS world). Basically they could enforce that only a single getHeader payment is made each slot. Then they have strong cancellation guarantees, which may be quite valuable to the builders. And if the builders end up only sending blocks to that relay, then the validators have no choice but to connect.
