The thread wasn't about discouraging IUSE defaults, rather to decide when they are appropriate. You cannot omit "pkginternal" from USE_ORDER, because you will break all of the packages whose defaults are either critical to the package, or prevent a REQUIRED_USE conflict. If that means IUSE defaults are the wrong solution to those problems, then it would be beneficial to have some "Guidelines for IUSE defaults" so that developers solve the problems correctly.
