Is there some quality, durability or other reason for the wipe?
Or, is it just cosmetic, and essentially unnecessary?

A good wipe can remove traces of flux, some types of which may over time
cause an unsightly greenish corrosion on the pipe and fittings.

Anyway, its just cosmetic, 'cause when talking about sweated copper
plumbing joints, "The solder you can see isn't doing anything useful."
