So did you miss like 5 billion notifications about SDKv1 becoming unsupported? Yes it is unfortunate, but C3 is already held up by so many constraints and legacy support features it's makes improving it much harder. At some point you have to let go of things.

There is also the LTS version, though I dont know much about it.
