This seems to have some overlap with the recent functionality announced by Databricks (as an internal/proprietary feature): https://databricks.com/blog/2021/10/20/introducing-sql-user-defined-functions.html
Is that understanding correct? Can you compare?
I am wondering if, similar to the Databricks feature, OSS Spark should have a more holistic way of handling this as opposed to copying Hive's syntax for a limited subset of the functionality.

You are right . The functionality in Databricks's Spark is more powerful than this.I did not know about that before you mentioned it.Mybe this is excess.

Might be:
"| CREATE TEMPORARY MACRO IDENTIFIER '(' colTypeList? ')'"
to support no arg macros.
The colTypeList is optional.
