Is there currently work on "openhab 3"?

The plan is to remove 1.x compatibility in order to permit a newer version of Java. There are possible plans to have3.x communicate with 2.x for v1 bindings support. There were a couple of survey threads trying to track usage of v1 bindings.
OH3 needs to get rid of the Java 8 restriction,

EDIT: poll, not survey.
