How is the creation of more and more hard fork helping Bitcoin?
First of all, the purpose of stacks is to allow bitcoin’s functionality to work better without hard forking. It is a completely different project that is only connected to the blockchain of bitcoin but not a hard fork. It doesn’t change anything to bitcoin’s protocol. Stacks is closer to a bitcoin layer.
To answer your question, hard forks are trying to improve and address all the other problems in the blockchain but it also brings great risks because it challenges the security and stability of the blockchain.
Is this something Bitcoiners would like?
It may seem promising but I don’t think it would be the magic solution to bitcoin’s scalability issues. It might help but I am almost certain it will not contribute greatly and magically change the system. But I would be happy to be proved wrong.
