Here are more use cases of the "earliest_timestamp_wins" resolution method:
1) Applications where the record of first occurrence of an event is
important. For example, sensor based applications like earthquake
detection systems, capturing the first seismic wave's time is crucial.
2) Scheduling systems, like appointment booking, prioritize the
earliest request when handling concurrent ones.
3) In contexts where maintaining chronological order is important -
  a) Social media platforms display comments ensuring that the
earliest ones are visible first.
  b) Finance transaction processing systems rely on timestamps to
prioritize the processing of transactions, ensuring that the earliest
transaction is handled first
