Does OpenShift 4.x have the same stretch cluster latency requirement as OpenShift 3.11?

Issue

• For OCP 3.11 there is a requirement that the arbiter site should within a 2ms latency window for communication between the primary and secondary sites.
• Does the mandatory 2ms latency still apply for OCP 4.6 Stretch clusters?
• The arbiter site will be relocated and there is a possibility that communication with primary and secondary sites may increase.
