I have no idea what you are on about. CoH1 had fences, you couldn't vault them, needing a 40 meter jog to reach a point 15 meters away was a common criticism and vaulting was an often requested feature. People were pretty happy when vaulting was confirmed in the sequel.
Ok, I'll rephrase it.
Vaulting is like going through bushes that slow the infantry going through them a bit that requires an extra click - bushes provide cover (like fences) and can infantry can go through (like fences in CoH2, but the latter needs more clicks). Thus, I regard vaulting at a glance that a very similar thing would be able to happen in CoH1 without actually implementing vaulting, I cannot see the issue with it in gameplay terms, and an argument against vaulting is really just an argument that "infantry should not be able to move past these parts of the environment on maps" because a number of specifics of vaulting are hardly nonexistent in CoH1.
And yeah, I totally wanted vaulted too. "Why can't my doodz go over this fence to the northwest end in Semoskiy" was an very common thought in my head.
