I don't think it's a big problem. After users understand the semantic, they
can easily work around it, by not putting grouping columns in agg list, or
turning off the config.
Well, it looks better if we can deduplicate it automatically, but seems
it's not that easy, according to this PR. Maybe it doesn't worth.
