Just on that, WR (World Rugby) came out with the following a bit over a month ago:
"Unique system introduced to mitigate the risk of some teams not being able to participate in all events and to determine Series rankings and decide relegation in 2022 ...
"... <snip>... Noting that Great Britain will compete in the opening two rounds, a points system will be developed that promotes fairness for all competing teams, including those who comprise Great Britain. This will also recognise situations where teams may not be able to participate in any rounds owing to COVID-19."

This means winning in Dubai might not be is not as great as it seems. The difficulty is, AFAIK, the details of this "unique system" are yet to be released to us, the great unwashed.
What could it be? - some guesses:
- Using win percentage instead of table points to order the standings?
- Allowing teams to drop their two lowest tournament results?
- + perhaps no relegation for a 3rd season straight?
