The problem is that everyone wants to see it just from their vantage point.  It is much work to see it from anyone else's viewpoint, let alone attempt to see a multitude of viewers.  It certainly helps to have to sit in someone else's seat for a bit.

Another part of the problem is "push and take".  On a recent project I was told to use two SMT connectors (that would receive edge fingers, so they were rather tall).  I took one look at the spacing between them and said nope--not for our hand-assembled boards.  A soldering tech was then asked if he could solder it.  Yes he said.  I put my foot down and went through-hole anyhow.  Later on the tech thanked me that he wouldn't be seeing those two closed-spaced SMT connectors.  Thing is, he could have soldered it, with much work, push come to shove.  After all, on his end, by the time he gets a board it's too late to change the design--so he might as well claim to be able to solder anything.
