You don't need a pretty wiped joint to join lead to copper. Merely a
decent seal between the two.


Simply running solder into the join would not have passed inspection for
a professional job.

You have provided no evidence of that.

The solder had to be built up in layers to give
the thick "bandage" to guard against leaks. The wiping wasn't just to
make it look pretty.

You are comparing a but join where solder is built up as a bandage, and
a join where a copper pipe enters a lead pipe for 25-50mm.

They simply do not compare. It suggests you have never connected a
copper pipe to a lead pipe. There is no need for layers to guard against
a leak.
