Lead solder is also against the water bye-laws (like local city ordinances) in most places here now for potable supplies. It only applies to new work, and apart from lead-solder joints there are still plenty of pre-WWII properties with a soft lead service pipe.
If/When lead solder does get completly banned from sale here, I'm going to lay in a big supply of it before the day. Some older parts just don't take to the lead-free stuff.
