PEP 227 mentions using := as a rebinding operator, but rejects the idea as it would encourage the use of closures.
Well, anything that facilitates rebinding in outer scopes is going to encourage the use of closures, so I can't see that as being a reason to reject a particular means of rebinding. You either think such rebinding is a good idea or not -- and that seems to be a matter of highly individual taste.
On this particular idea, I tend to think it's too obscure as well. Python generally avoids attaching randomly-chosen semantics to punctuation, and I'd like to see it stay that way.
