Using FreeBSD (or any other BSD for that matter) makes you too dependent on Linux libraries and Linux software that is poorly designed, bloated, and frequently without support for *BSD because it was dropped by LinuxBros. I actually think it would be easier from a maintenance standpoint, as well as a usability standpoint, and purely for the sake of "debloatifying" to develop new software and libraries (or just fork the already existing ones before they drift past the interoperability event horizon), so the BSDs don't have to deal with software written for a horribly-designed series of OSes that drift further away from UNIX every day. If the BSDs could work together on a BSD Alliance (a FreeDesktop type group for BSD that focuses on sanity rather than chasing stupidity) the BSD software ecosystem would be even better than it already is. Also, if the FreeBSD xorg port is based off of NetBSD's xorg impementation so it doesn't pull in all of that Linux crap, that would be great.
