Motivation: sbt-mima-plugin 1.2.0 reports binary incompatibilities against 1.0.0 that 1.1.6 silently skipped, mostly static forwarders and companion members. The Binary Compatibility job fails on this branch with 235 problems across ten modules under Scala 2.13, and stops before the Scala 3 lane runs. Modification: Add a mima-1.2.0.excludes file to the 2.0.x.backwards.excludes directory of each affected module, listing the filters MiMa itself suggests. Every entry covers a change already made on this branch for 2.0.0 - removed deprecated methods, reworked internal APIs, the ReceiveTimeout and dns IdGenerator signature changes, and the dropped Akka 2.6.4 serialization manifests - so they are excluded rather than reverted. Filters that only Scala 3 reports are kept in a separate section of each file. Result: mimaReportBinaryIssues is clean on both published Scala versions. Tests: - sbt "++2.13.18!" "all actor/mimaReportBinaryIssues stream/... (10 modules)" - success - sbt "++3.3.8!" "all actor/mimaReportBinaryIssues stream/... (10 modules)" - success - removing actor-testkit-typed/.../mima-1.2.0.excludes reproduces the failure, confirming the excludes are what make the check pass References: Refs apache#3535
