I have seen this indecision as a death knell on a few projects. You really just have to pick something, especially if you stop developing the soon to be deprecated tooling. If it takes you two years to pick a new method, then all your developer community has to sit on their laurels. They can't invest in the old platform, they can't invest in novel tooling of their own, and they can't build with the new thing because you haven't chosen it yet.
