I think what we've learned is it's not as easy as that to change bitcoin, but that can also be a good thing. However, if an alt comes along that is revolutionary and has something that makes it far superior to bitcoin then I think they would be forced or hastened into implementing it because the alt would be in danger of surpassing bitcoin eventually and that's something nobody wants to happen. I do hope bickering between devs and interested parties wont cause damage in the future.
