I think they already handle this case by accident, because distributed clocks are unreliable and inconsistent anyways.

Now, I don't think they worry overmuch about general or special relativity at this point, but if we start putting datacenters in orbit that will become an actual issue.
I'll wager we'll start seeing Edge Compute and CDN features on the very large satellite constellations (Starlink, etc) soon. Initially this will preserve bandwidth between satellites and with the ground stations. This will be a big upsell feature. The Quant folks would pay more for those sweet low-latency links...
