The increase in de-soldered plugs and connectors certainly increased when we stopped using this, the increased heat required seems to have caused an increase in poorly soldered plugs and connectors. The joint will look good externally but if the part being soldered is not hot enough an air gap will exist inside causing arcing and heat build up.
None of the the stuff available through RC distributors contain lead and unless you plan on eating it there is really no risk at all.
