I'm one of those who gave up waxing. I have well over 30 days since my last wax (I'm sure BA has gone much longer).
I haven't really missed it other than one brief moment when I first got to the hill. It was packed powder and my board felt very sticky when skating in the lift line. Interestingly, very quickly into my first run it seemed to get faster and ceased to be sticky after that.
With regards to the OP, back when I waxed my board I would usually hit the tip and tail with a little wax, but I wouldn't work too hard at it, or scrape it too thoroughly.
