Ballow Then, you'll have to see that with the devs or the SLR team.
However, I don't really agree when you say "And now a 3rd party application is needed to fully utilize the functionality that an app previously had?"
Whether it's DLNA or XBVR, no matter what, you're always using a third party application to access your files, the only thing is that going from your DLNA server to XBVR, it's going to take some work, that's all, but once everything is set up, it's just maintenance afterwards.
