It wouldn't hurt anything if a shingle stuck to the underlayment .
It's
already nailed or stapled to it. The "DO NOT..." is just a simple
way of
saying "It's not necessary to and you wouldn't accomplish anything
if you
did..."

Not exactly true. That plastic strip also happens to be the nail
line, at
least in three tabs. Some manufacturers think it provides a little
extra
nail holding capability.

The plastic strip is flimsy, and it's on the bottom of the shingle.
