Apparently, FB builders artificially inflate bid values by incl. withdrawals. They outbid other builders at the expense of proposers who miss out on actually more valuable payloads.

FB should stop doing this, or relays should stop accepting bids from such builders

This is how the relay spec is written, no one is inflating anything. The real discussion is whether the spec should be changed. And the proposer in this case lost out on $21, the urgency is overblown.

How is including withdrawals in bids not inflating them? This makes payload comparison inviable, and --min-bid as well. Moreover, it's not about some absolute $ terms, it's about trusted entities remaining trustworthy.

In order to capture all possible mev edge cases the spec was intentionally designed to measure the change in balance of the proposer before/after the block. It's not elegant but it's robust. The question now is whether to carve out an exception for withdrawals or redesign the whole system.
