[arch-general] Why was /usr/lib/cups/backend/parallel dropped from cups?

Guys, After updates to cups yesterday, printing to a laserjet4 stopped working. After searching, I discovered /usr/lib/cups/backend/parallel did not exist. Why was it removed from cups PKGBUILD? The size is minimal in the days of gigabyte drives and there are still many parallel and serial printers. -- David C. Rankin, J.D.,P.E.
