Seems like
                      I’m late to the party here, so rather than
                      skimming through the entire thread let me just ask
                      a question:
                   
                  Has it been
                      considered to provide preconfigured “Warning
                      Profiles” with 3 simple levels (picky, standard,
                      relaxed) ?
                   
                  I see two
                      big workflows here:
                  (a)    I’m stuck
                      with a big pile of legacy code, please don’t
                      defocus my attention with lots of unnecessary
                      warnings.
                  (b)   I’m writing
                      some new code, please give me picky warnings to
                      help me write clean code.
                   
                  In my
                      experience, the real annoyance is having to deal
                      with each warning individually, and that on a
                      global scope. I see some warning in the Problems
                      view, what the heck is the right entry in
                      Preferences to turn that beast off ?
                   
                  Ideally the
                      tool would be intelligent enough to know what
                      files I have touched with new code (and enable
                      picky warnings on those files before I checkin),
                      but leave the old code alone without extra
                      warnings unless I ask for them.
                   
                  I’m curious
                      what the outcome of the survey will be, but IMO
                      there is no “one size fits most” approach to the
                      warnings.
                  It’s better
                      to make it easier fit a user’s situation (type a
                      or type b, and allow easy turn-off of individual
                      warnings that annoy me).
                  Rather than
                      investing too much into a good single default.
                   
                  
                    Thanks,

                  Fyi, the
                      survey asking about line numbers and compiler
                      warnings is now live. We will be promoting it on eclipse.org
                      and the usual social media channels.  Feel free to
                      help promote it. The survey will end in 2 weeks.
