   Yep, the work we did was exactly that, to expose this existing Iceberg 
functionality via SQL syntax. See PR: https://github.com/apache/hive/pull/3222
   
   It was ultimately abandoned, because we wanted to reuse the SQL standard 
`FOR SYSTEM TIME BETWEEN ... AND ....`, but the semantics of what Iceberg 
returns (appends that happened during this time period) is different than the 
semantics of the SQL standard (returns all rows that were active during this 
time period - so rows could have been appended before the time window as well). 
At the time we found no justification for introducing a new, Hive-specific SQL 
syntax for this.
