No we do not. ean13isbn works nicely and all the way up the chain to
luatex, in fact we have just changed to it because of these reasons.

I have one "complaint" though about ean13isbn. To make the title (ISBN
123456..) of the SAME size as the bar-code is NOT a requirement of the
standards, so allowing for a slightly larger size and a bit more detached
from the bars would make that part more readable (to humans), and so a
better bar-code.
