Is it worth emulating Oracle built-in routines in Snowflake and BigQuery

This is probably an Interesting if not a Poll leading to interesting conversations.

If you already know, Orafce is an extension that emulates in PostgreSQL, a subset of functions and packages from the Oracle RDBMS.

This extension is very helpful while porting Oracle applications to PostgreSQL, avoiding application code rewrites in a performant way.

Do you think it is worth having a similar emulation of Oracle functions/packages on Snowflake and BigQuery ?
