Just catching up on this thread: https://lists.apache.org/thread.html/17ecae7960572e3cad9ba734ea15d55a337422e27ce08d2297a1e830@%3Cgeneral.incubator.apache.org%3E
My reading is that it’s up to a podlings discretion whether to use a -incubating suffix in their maven coordinates. I move that we remove the -incubating suffix from our next release forward. Steve
