km/h is derived, at least with an integer multiple of seconds, from SI units. mph and knots are not. I would prefer to keep one default unit per tag, consistently, everything else leads to confusion.

Hi, Currently, le wiki ([1]) suggests that maxspeed has to specify the unit "knots" when it's not km/h. But "knot" is the unit used worldwide on waterways. Why should we add something obvious on all waterway elements ? Could we suggest that the default unit for maxspeed on waterways is "knot" and the default "km/h" remains for highways and railways ?
