What it the force-update annotation useful for here?

Isn't one year a bit too much?
It means that your pod can take up to 1 year to be removed.
I would keep it lower, up to a day?

I chose a ridiculously long amount on purpose to ensure that shard drainage would have enough time in worst case scenarios.
i.e. if there are jumbo-chunks that we cannot automatically drain (because the user should decide the new shard key) - then that will require user intervention and I would like to give them more than enough time to do so.

I think MERGE or STRATEGIC don't change anything here so I would not specify it and keep the default value of STRATEGIC, but it's a nitpick.
