Say what you will about your own methods of pipe filling, lighting, smoking, etc.
I have also heard so many conflicted stories, most of which I think are the devils advocate just for the fun of it, and I don't mind. Good conversation has always been hadover a pipe, right?
Truly, I have had no problems with loading my new pipes up to the rim and just smoking. I find it too tedious to care. Heck, some collectors buy pipes that will never be smoked, and will be passed on to the next one who will never smoke it. At least when this pipe gets handed down to the next lucky sap, will know it was smoked with love.
I used to delicately use matches and hold the flame over the pipe and slowly rotate it. Every pipe I had smoked since I stopped doing that has built cake just fine.
