There's still the whole "Too much of a good thing" problem. It's conceivable to put so much teflon on a fitting that you can't even thread it. It also makes it harder to tighten up fittings and increases the risk of getting shreds of teflon in your system. Not to mention the nightmare of having to clean it off the fitting if you ever have to disassemble things.
We usually don't bother with more than 2-3 wraps of teflon on my team or at my company for these reasons. If you properly tighten the fittings, this is more than enough to get a good seal, and little enough to not cause you problems.
