Actually, it is kinda new to us, we used to have a common take off and landing crosswind limit, but it got changed around a year ago into different ones for landing and take off. Remember though that those limits are including gusts, not steady wind and are applicable to narrow runway operation as well. A 25 kts crosswind limit on a wet runway is fairly low though considering that the autoland crosswind limit is 25kts as well (doesn't matter if wet or dry). Only single engine autoland crosswind limit is lower at 20kts.
