AS7 testsuite - maven.test.failure.ignore vs. surefire.test.failure.ignore

I have problem with AS7 TS internal surefire.test.failure.ignore property to ignore tests failures. Ignoring failed tests can be useful for code coverage or when you are building unstable version of AS7. With this property we are adding requirements for users because they will need to search for all properties and can't rely on standard Maven knowledge.

Is there any hidden motivation for surefire.test.failure.ignore property? I can't recall any.

Current command:
./tools/maven/bin/mvn -e -s tools/maven/conf/settings.xml install -Dts.smoke -Dmaven.test.failure.ignore=true -Dsurefire.test.failure.ignore=true
Goal:
./tools/maven/bin/mvn -e -s tools/maven/conf/settings.xml install -Dts.smoke -Dmaven.test.failure.ignore=true
Suggestion:
Replace surefire.test.failure.ignore property with standard maven.test.failure.ignore
