Proximity blocking will effect back walking in footsies range. If they throw out an attack it will make you stop walking and block even if the attack doesn't hit.Classically, in back-to-block fighters, one can hold down and back to block while remaining in place (Crouching, however). So not really. It changes footsies for sure, but they're very much intact.
To use a recent example in SF4 play:
You can see the two characters, particularly the vega player, playing a heavy footsie game, throughout whenever the two characters are close. (This is not the perfect example, but it's all i can recall of recently in that game)
