Thanks for raising this discussion, @Alex. I agree to drop supporting of scala 2.10. But I will prefer to make scala 2.11 as default. Because most of the interpreter depends on scala 2.11. Although some interpreters support scala 2.12 too, but scala 2.11 is still the most popular one I believe. Take spark as example, spark 2.4.4 is the latest release of spark, its default scala is still 2.11.
One concern of dropping scala 2.10 is that it might break some interpreter, such as beam, scalding, scio, I am not sure how much work needs to be done to support scala 2.11 for these interpreters. And I am afraid the maintainer of these interpreters are not active in community now.
