   Geopandas: `z : float | array_like (default 0)`
   Sedona: `ST_Force3D(geometry: Geometry, zValue: Double)`
   PostGIS (what Sedona generally tries to follow): `geometry 
ST_Force3D(geometry geomA, float Zvalue = 0.0);`
   
   Yeah, support array arguments isn't too common for SQL, and it's honestly 
slower for Sedona, since it requires a distributed shuffle + join 
(`_row_wise_operation()`). But we do have a convenient way to do it. Model it 
off the implementation of `.segmentize()`. I noticed a few bugs in 
`.segmentize()`, so I submitted [this 
PR](https://github.com/apache/sedona/pull/2507/files) to fix a few things. 
Here's [the 
link](https://github.com/petern48/sedona/blob/22bf0d73daccec0c1001847f60712007be02f135/python/sedona/spark/geopandas/geoseries.py#L1076-L1086)
 to the `.segmentize()` implementation in that PR. You'll likely need to copy 
over [this 
change](https://github.com/apache/sedona/pull/2507/commits/0f448a4d772ea55b969fb988b68d4e809859d7de)
 for lists to work properly or wait for that PR to get merged.
   
   Great Question!
