Instead of block thresholds, use utxo bits to coordinate size changes (larger and smaller should be allowed).

There is no reason for miners to be involved in a decision to change this aspects of the protocol.   Plenty of other ways to coordinate.

Otherwise someone can make it seem to a miner like 99pct of nodes are ready for a larger weight.... even though that's false.

I have a proposal that would allow each user to optionally configure the
maximum block weight at a support threshold.

It recognizes that there is no need for off chain bickering, by
providing a mechanism that lets each users freely choose their own
parameters while still maintaining full coordination of any changes.

The BIP can be found here:

It is worth noting that this proposal does neither gives more power to
miners nor reduces decentralization. Miners still rely on their blocks
being accepted by economic nodes to sell their minted coins. This
proposal doesn't change that.
