> [Java SDK harness|https://github.com/apache/beam/blob/d82d061aa303430f3d2853f397f3130fae6200cd/sdks/java/harness/src/main/java/org/apache/beam/fn/harness/BeamFnDataReadRunner.java#L223] doesn't support it yet which is also safe.
> [Go SDK harness|https://github.com/apache/beam/blob/d82d061aa303430f3d2853f397f3130fae6200cd/sdks/go/pkg/beam/core/runtime/exec/datasource.go#L273] only supports splits if points are specified and it doesn't use the fraction at all.
> [Python SDK harness|https://github.com/apache/beam/blob/d82d061aa303430f3d2853f397f3130fae6200cd/sdks/python/apache_beam/runners/worker/bundle_processor.py#L947] ignores the split points meaning that it may return an invalid split location based upon the runners limitations.
