And please remember that some of us still try to squeeze out a little bit with primary extensions if required in certain situations. Also welding on some coatings will fail even when the surface is ground to clean metal. Embrittlement or something similar.
I'm not particularly fond of having a collector on a wire flopping around under my car possibly puncturing a front tire or severing a brake line or igniting my oil soaked engine diaper from sparks flying etc. etc.
