Yes, every upholsterer has run over a welt and ruined a project, which is no big deal if it's fabric or vinyl. If it's leather,ultraleather,ultrasuede, or suede, it is a big deal. Why invite trouble? My welt feet almost never come off my machines, and every sewing room with commercial sewing machines in it that sews welts is the same way.
I think we're talking about two different things here. I agree, a standard presser foot wont work, however if the presser foot is a zipper foot it will. Hopefully this clears up any confusion.
