There's already at least two big-name alternatives to Oracle Java: The OpenJDK and Amazon's Corretto. If you're suggesting Google might make their own "supported" OpenJDK build, then sure, that might be worth something. That's different than moving away from JVM entirely to a different compiler target, as suggested by the parent comment.
OpenJDK is like 90% developed by Oracle with smaller contributions from other partners in the Java community, including the JEPs that bring Java forward.
