thanks a lot Piotr for this return on experience: this help me a lot 
anticipating reality vs theory!

this makes me feel we should try on maven-studies.git = the perfect location to 
do stupid tests

I'll have a look at how things are configured in Log4j2 and try to play with 
test branches in maven-studies

please others don't hesitate to test for yourself what we can implement vs what 
we dream then reading OpensSSF Scorecard and other best practices

Regards,

Hervé
