I had some RM6 transformer windings made with tracks of 6mil width and 6mil spacings. Some came back with shorted turns on windings - it sure as hell had 100% tested continuity - even including some unintended short cuts.  It took a microscope and sharp scalpel to find and fix. If there is a good reason for tight spacing I'm all for it and do it. If there is ample space there is no need to use tight spacing. In my experience when so close to a solder joint too, it is just asking for trouble.
