Description

Policy setting to gradually require a higher feerate to be included in block (ie, make a smaller block if the impact on fees is negligible)

Satoshi's Bitcoin client had this, might be good to restore it.

Contributor guide

Research direction
Investigate the current block creation and transaction selection code in the repository. Look for the minimum feerate parameter and how it is currently applied. Then design a function that increases the minimum feerate based on the block's filled ratio. Implement the policy setting and add corresponding tests.
