Pavel Tupitsyn commented on IGNITE-25902:
-----------------------------------------
[~v.pyatkov]
1. Please elaborate, where we can't use it?
2. `ClientTransactions.beginAsync` takes `observableTimestamp` and passes it to
the server as a read timestamp, so we have everything we need on the client to
expose the read timestamp to the user
