TFA reports full dba_feature_usage_statistics to MyOracleSupport

Those who deal with MyOracleSupport (MOS) regularly will have noticed their demand for Trace File Analyzer (TFA) diagnostic collections.
Few will know they are also providing a full content of their DBs DBA_FEATURE_USAGE_STATISTICS view; at least when running the parameters

tfactl diagcollect -database <DB_UNIQUE_NAME>

The report calls tfa_home/resources/sql/db_feature_usage.sql and it's result is stored in the <hostname>.tfa_<timestamp>.zip file.

I did not find any mention about this behavior in the documentation, so it might be worth to post about it.

This is at least true for version 18.3.0.0.0 (latest version available at 2018-09-04)
