It's funny they were so quick to jump ship when it meant they had to do little to no work, but now that everyone wants a proper rework, the jmods are nowhere to be seen.
You keep making this accusation and it's farcical and insulting to the developers. If they made decisions based on what to implement to skip on work, they would be fired. We far more often have the exact opposite problem, where developers publicly promise far too much, or privately believe that more work would make the project better, and then do voluntary overtime in order to make that happen.
