The devs seem very reluctant, but they will definitely have to do something about it. I just hope by the time a decision is made, it's not too late. If I have to pay fees $100 just to transfer $200 worth of BTC, then this is not a good alternative peer to peer electronic cash system.
People are going to try to look for cheaper alternatives and the growth of the Bitcoin network will reduce.
What cause reluctance of developers to fix holes that are exploited by Ordinals and Runes?
There is idea and proposal from Luke but it is a type of censorship that is not supported by Bitcoin developers. I agree with fight for freedom and against censorship because it is core value of Bitcoin and vision of Satoshi Nakamoto. We don't live our life with Satoshi Nakamoto's vision but if it is good practically, it can be continued. In contrast, if the vision is no longer good practically, something must be done to fix exploited holes.
