Copper to lead is already well supported. So the only thing the solder

Given that lead is easily malleable, the joint is not that well
supported in the presence of knocks,gravity and vibration.

The copper pipe going inside the lead is going to reinforce it at that
point. And why wouldn't you support the copper pipe where it joins the
lead?

Because unless it's in the regs, plumbers simply won't bother.

True. Hence saying how to DIY it in this group.
