@soatok @f4grx I am software engineer working on RHEL. What you demand is never going to work. Marking old and insecure features obsolete and disabled by default is a way to go. It takes a lot of time. But any serious improvement cannot be done by re-inventing the wheel. It might be too slow in your opinion. But industry works that way for a good reason. Dnsflagday.org might be example how to move it forward.
