As far as I have seen from https://github.com/SonarSource/sonarqube/blob/4e94db27ded24dbe907970c21a96e75f8d581a33/sonar-plugin-api/src/main/java/org/sonar/api/CoreProperties.java#L344-L345, the analysis parameter sonar.links.scm_dev
is deprecated.
But https://docs.sonarqube.org/latest/analysis/analysis-parameters/ still shows it as valid property, not as deprecated one.
