This sort of thing is definitely in the class of "are you experiencing problems? if not don't worry about it".

If you are experiencing problems, this might give you an angle to think about that you hadn't otherwise, if you just naively assume Wifi is as good as a dedicated wire. Modern Wifi has an awful lot of resources, though. I only notice degradation of any kind when I have one computer doing a full-speed transfer for quite a while to another, but that's a pretty exceptional case and not one I'm going to run any more wires around for for something that happens less than once a month.
