I don't understand your argument about ecosystem being far more important. People ceasing use of any of the tools necessarily removes them from the ecosystem and community. They have no reason to care about those things.
Definitely. At that point, they need to weigh the cost of migrating their existing project to a new platform, or to maintain the patches that will allow the old platform to have the flexibility they need.
It's important to remember that they aren't being removed from the Elm community - they can still use the packages, the compiler will still get updates they could presumably rebase their patches on.
