   > I think for snapshots you only want to delete files that are made in 
commits after the original import, that should be possible but complicated. 
Basically just delete everything added after the first iceberg snapshot.
   
   Yes and no. That's the case for snapshot but what if someone creates an 
Iceberg table with GC disabled and uses it to just promote files written not 
through Iceberg? Then deleting data beyond the first snapshot not safe too. 
Maybe, we can take `snapshot` table property into account.
