I agree that it should be toggleable if it ever happens... I don't see it happening, though.
For it to be necessary (considering that Jorb and Loftar dev for the default client, which has an ortogonal fixed camera) they should need to properly allow the "bad cam" as official.
But that's complicated. There's a reason they are not doing it: until rendering distances are way (way) bigger, the non-default camera (and hence the addition of skyboxes) would be incredibly ugly. I mean... ugly as in "extremely unprofessional for a commercial game"
Before we see larger terrain rendering distance, with landscape on the horizon and trees not popping up 10 meters ahead of us, I doubt we'll ever see the free camera and skyboxes.
