I've run into a few cases in which bug reports were closed as status-bydesign where I really feel that the design process should be rethought.
Is there a way to say, I understand you think this is not a bug but I think you should reconsider? After all Jeff keeps saying he was against meta till he saw the light; how can we shine the light in his eyes?
I'm guessing that removing the tag is inappropriate...
A prime example of this is Migrated questions lose their accepted answers. I had some questions migrated from SO and haven't followed up on them since; why do they show up as having no accepted answer? It makes no kind of sense.
