On allot of shingles "DO NOT REMOVE" is printed on the strip. For some

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.

Have a cite for that? How would it add any holding capability as the
holding capability is in the wood deck, not the shingle. That thin
strip will also not add anything to keep the nail from pulling through
the shingle.
