   @snuyanzin @MartijnVisser  Why do we necessarily have to align our semantics 
with Snowflake?
   
   i found spark/presto/doris/max_compute all follow the semantics without 
duplicate. 
   I personally still think that aligning behavior with the majority of vendors 
might be better, as it would not cause too much confusion for users when they 
switch to a different engine. Unless the behavior is very unreasonable, we 
should not need to change the semantics. What do you think?
