There are no known proposals to change the current mechanism for including transactions in blocks to introduce more explicit censorship resistance measures, such as the ones you described. While it is theoretically possible to introduce new protocol rules to achieve this, it is unlikely that such changes would be accepted by the wider Bitcoin community and would likely require a hard fork of the network.

In general, the best way to ensure censorship resistance is to maintain a decentralized and competitive mining landscape, where miners have incentives to act in their own self-interest and include as many high-fee transactions as possible in order to maximize their profits. This helps to ensure that the network can continue to process and validate transactions without interference or manipulation by any individual or group of participants.
