-- Relax exact version requirements and comment out code generation tools
-- in build-system dependencies.
--
-- 1. Comment out grpcio-tools and mypy-protobuf as these are only needed for
--    generating protobuf code, which is already included in the distribution
--    tarball.
--
-- 2. Relax exact version requirement for distlib to allow using newer versions.
