over 20+psi of boost, yes that is likely the case. I've personally run the gt28rs at 18psi on internal wg without any issues at all. With a built engine these cars will produce 650+whp at those levels.
If you are shooting for over that with much more boost, then it might make sense, however I cant imagine many people are looking to go upwards of that, and yet so many run externals. They cost more, and as Ron has noticed, are a pain in the *** to install in our car if you want to recirc. Don't mean to derail, just my .02
