Compatibility with PostgresPro Enterprise autonomous transactions

[FuzzyLogicMgn]

Hello,
The documentation says that autonomous transactions cannot be used with pg_variables.
I wrote a small test case using pgv_get, pgv_set and autonomous transactions and it worked without errors. Can I rely on pg_variables to work in autonomous transactions or are there scenarios where there will be errors?
Are there plans to support using pg_variables together with autonomous transactions?
