Review Comment:
> IIUC, the proposed change 'Move the configurations to ...' of the FLIP
means that we can just make the move without having to keep the old positions
because we haven't changed these configuration option names, so If there are no
objections, you can remove the option from the original classes.
Yes, it's the original plan. But during the
[discussion](https://lists.apache.org/thread/n52smchwgr6qfg3tfvmxpdshk8obgor2),
Xuannan mentioned the API compatibility guarantees. The only concern is that
although there's no constraint on the Experimental API, and in theory, users
should not directly rely on table-planner in their projects, we're still
determining whether users rely on these variables in their code.
