Well Rob,
Just a question before my comment.
I assume you are definitely talking about 4-way connections? (wasn't
absolutely sure with description
after the +)
If so then I would say that they are a very bad practice.
I kind of look at it the same way as someone who
does all kinds of rule bending in the software
than complains like crazy when the design doesn't
translate into the next version easily or at all.
