Surely this argument would then apply to everything else in the database too? Yes, population changes over time, but roads also change, commercial and industrial zones change, railway lines change, new housing estates appear, etc. Currently we have data from npe mixing with up-to-the minute gps data. The only track we have is the last-edited time (I think?). In practice, things are still working ok. Yes, it might be nice to tag population or other db features with a date, but this would be a feature in itself, and wouldn't seem a good reason to reject the population tag.
