   From an end result perspective I prefer the coalesce direction. I think 
`resolve_duplicates` might be a nicer keyword. With my user hat on I don't care 
too much about HOW that happens under the hood so maybe this also makes things 
more flexible if we change later. Additionally, special caseing kwargs to not 
manage certain situations adds complexity.
   
   I think if the user wants to decide the details of how things are handled 
they can opt out of `resolve_duplicates`. I just opened a PR for datafusion to 
try and make resolving ambiguous column dropping and reference clearer so they 
can actually do so without just doing it in SQL.
