Hdri backdrop or "finite dome"

Hello,
I know that this question has already been raised, but I’d like to know if the D5 team will soon take this problem into account.

I’m a Twin motion and Vray user who can create an HDRI backdrop, i.e. a configurable physical object; this option must be ticked in Vray (finite dome).

At the moment I’m not really able to use D5’s hdri, whose background keeps a fixed size when you zoom in…

thanks
