Yes. But you'll still load them. If you have lot of routes, turning up
VRF takes long time, as you'll need to reload everything to get those
two routes you actually need.
Convergence also is impacted, as every change is visible to you, and
you need to drop them, even though you weren't interested to begin

Employer of mine had well over million VRF routes, with small subset
needed in given VRF, it's quite a bit of useless signalling.
