I have faced lots of BBs and headtubes. I have yet to have one that is square from the get go. SOme where pretty good but never square, the "out" section is always where the chainstays are welded or brazed in. More surprising is the headtube. The part is often "finished" before becoming part of the frame, but the faces are still off every time.
Does it matter? For the guy that whacks his junk together with a twobyfour and a hammer, ... NO. For guys that want their stuff right,... it matters. You can hone a cylinder with emory cloth and get by with it but a proper hone does it right. Get by or do it right, your choice.
