View created by Athena query not accessible to Glue Jobs spark context, unless I change ViewExpandedText. Is this ok?

When a view is created by running an Athena SQL query, it appears in the Glue catalog but errors are raised when querying the view in a Glue job or a Glue Spark context.

I am able to make the view available to Glue jobs and query it with PySpark by changing the Glue table's ViewExpandedText property to contain the SQL of the view (i.e. the SELECT statement of the view), and removing the "SerDeProperties.Location" from the view. (See the code below.)

This is the opposite of what is documented for ViewExpandedText - the official Glue API docs say this field is "Not used in the normal course of AWS Glue operations."

The question is: Is the documentation incorrect? Is the functionality I am taking advantage of officially supported? If it is not supported, should I assume that at some point in the future, changing ViewExpandedText to make the view usable in glue jobs will stop working?

Code to hack the view: gist

# Making an Athena view queryable in a Glue job
#
# When a view is created by running an Athena SQL query, it appears in the Glue catalog but errors are raised when
# querying the view in a Glue job or a Glue Spark context.
#
# Use this gist to programmatically update the view's metadata in the Glue catalog.
#
# After this you should be able to run `spark.sql("select * from mydb.myview")` without errors.
#
# Assumes you have created the view `mydb.myview` in Athena.
# For testing I used `CREATE VIEW mydb.myview AS SELECT 1 as Index;`
