Whether or not there are other modules available really isn't the point. I think it's rather bad form to remove a module that people are actively using. I have code that's "in the wild" that uses Config::Ini. Now, that code is effectively broken. The users can't be expected to port it to AppConfig or another config module. I can understand removing old versions and even dropping support but if modules can just disappear, then I will certainly reconsider my use of CPAN.
