+# We expect that TypeScript compilations will parallelize wider than the number of local cores anyway
+# so we should saturate remote workers with TS compilations
+# TODO(jperott): if/when we enable remote cache on CI, we would expect
+# to have many fewer TS compilation actions, so local worker might make more sense
