Look at
https://github.com/DataSystemsLab/GeoSpark/tree/master/sql/src/main/scala/org/apache/spark/sql/geospark
sql for an example.

Using custom function registration and functions residing inside sparks
private namespace should work.

But I am not aware of a public user facing API.
Is there any I am missing?
