xazax.hun added a comment. So having an analyzer-config option would be useful for those codebases that are expected to be compiled with less advanced compilers that do not elide copies or not doing it aggressively enough. Maybe it is worth to ask on the mailing list of the community wants to have an option for this? I am not sure though how often the end users end up fine tuning the analyzer. It might be nice to have a guide how to do that (and in what circumstances does each of the config values make sense).
