   > > Currently the preference is to avoid a third-party dependency for this 
issue, ideally fixing up the parser behavior instead to properly handle deeply 
nested input. See [comment 
here](https://github.com/apache/datafusion-sqlparser-rs/pull/1468#issuecomment-2414747574)
 for a bit more context on rationale From a quick look at recursive it seems to 
be a procmacro on top of the stacker library so that the same considerations 
should apply I imagine.
   > 
   > @iffyio, we had done some research on stacker / recursive in 
https://github.com/apache/datafusion/pull/13310 to verify concerns before we 
added it to datafusion: 
https://github.com/apache/datafusion/pull/13310#pullrequestreview-2424590466 / 
https://github.com/apache/datafusion/pull/13177#issuecomment-2465457730
   
   Sorry for missing that context when reviewing. So we would like to avoid 
using recursive for stablility, maybe try...
   1. vender the code from recursive
   2. use stacker directly, like 
https://github.com/apache/datafusion-sqlparser-rs/pull/1468
