Yes, I agree with you. I have opened a
[thread|https://lists.apache.org/thread/cl2876ytgyvyb0j12m7wtlvm1hsfjgmy] about
this issue in dev mailing list . Since these added syntaxes will not introduce
new public API, I don't think we need a FLIP and we can finish the discussion
on this issue.

> Partitioned table statement enhancement
> ---------------------------------------
>
> Key: FLINK-27237
> URL: https://issues.apache.org/jira/browse/FLINK-27237
> Project: Flink
> Issue Type: New Feature
> Components: Table SQL / API
> Reporter: dalongliu
> Priority: Major
> Fix For: 1.16.0
>
>
> This is an umbrella issue which is used to discuss the syntax enhancement
> about partitioned table. These new syntaxes are very useful for partitioned
> tables, especially for batch job.
> Therefore, I propose to support the following statement about partitioned
> table:
> {code:sql}
> -- add partition
> ALTER TABLE table_name ADD [IF NOT EXISTS] { PARTITION <partition_spec>
> [PARTITION <partition_spec> ...] }
> -- drop partition
> ALTER TABLE table_name DROP [ IF EXISTS ] { PARTITION <partition_spec>
> [PARTITION <partition_spec> ...] }
> -- rename partition
> ALTER TABLE table_name PARTITION <partition_spec> RENAME TO PARTITION
> <partition_spec>;
> -- show partitions
> SHOW PARTITIONS table_name [PARTITION <partition_spec>]
> <partition_spec>::
> (partition_col_name=partition_col_val, ...)
> {code}
>
