you have two problems with new formulations though. one is lead-free solder seldom works as well as the box claims. two, antimony is somewhat concerning from a toxicity standpoint though i'd say less than lead

i wonder if we don't just quit and go to brazing all joints. rod is pricier than solder and takes more heat but probably less toxic and certainly more dutable

Tin/silver soldering (~95/5) would probably be better than brazing for water supply piping as brazing will tend to anneal the hard drawn copper tubing, which isn’t desirable from a strength standpoint.
