Some people on this forum would have known about Bitcoin Core development and transaction relay policy which some people think would be about OP-RETURN and Ordinals, although Core developers did not directly mentioned any like that.

The users of Bitcoin Knot which is alternative means to run a full node is drastically increasing. It started from when MPR #32406 was introduced which will be part of the upgrade. It is about the OP_RETURN data limit increase from 80 bytes to 4 Megabyte. Definitely some people that like just only text and not image and other large files to be included on the blockchain will not like it.

Another thing is the Ordinals, BRC20 tokens and maybe other coming ones spamming the mempool to be blocked. Which means such transactions might be rejected even as they obey the consensus rule and valid. This probably make some people leave Bitcoin Core and started using Bitcoin Knot. Bitcoin Core node runners increased from 394 nodes to over 2000 nodes, although Core users are around 87% while Knot users are still around 13%, but there are speculations that Knot users might continue to increase and take over Core users. This may be very wrong but just a speculation.





I understood everything I read about this but except on thing. If there is upgrade to Bitcoin Core, is it possible for the Bitcoin Core developers to make some changes mandatory for the non-Core users? Like people using Bitcoin Knot to follow their upcoming October Upgrade? I am asking this question because I think Bitcoin Core developers against Ordinals while some node runners may like it as long as their transaction is not against the consensus rules.

If I make any mistake, you can correct me. I only have little knowledge about the politics and principles surrounding bitcoin.
