I think this is a simple feature that could provide more realism to the server. Currently there is no indication if it's cold or hot or anything like that. I think this feature could be a nice introduction which would provide a reason for different clothing during different days. For example maybe Monday it's 30c outside then you wouldn't wear a coat.But another day the temperature could be 15c and so on which would indicate to dress up a little warmer, etc. This doesn't interfere with anything and is a rather trivial feature that could be used by people.
This could also be combined with a new phone system to have a weather app.
