To be fair it's hard to say if the feedback about the date really had anything to do with it being back--it certainly could have, just as the date could have been something that was added back in a build by a developer due to a bug fix or some other internal change even before and/or unrelated to that feedback. That said, given that aside from posting in places like this the only other options that are available are providing feedback and/or entering bugs, it's certainly worthwhile to do it for something that isn't right or someone wants to see changed.
