But it's explicitly not a WontFix. It's a "we're sorry, for whatever reason this issue is not getting traction. We are closing it because whatever the issue or reason is, whether it's on our side or the reporter's side, or something else, this problem is not effectively handled by this issue". Closing as WontFix would inspire a thousand proclamations of "Google is never going to fix X!" when they may very well address it in the future. I don't think what Google's done is ideal, I agree they should add a comment. However "Obsolete" is probably better than WontFix unless they really did analyse the problem and explicitly decide not to fix it.
