To Bridge or Not to Bridge

Is there any disadvantages to using a bridge interface when there is only one port slaved?

I know obviously it adds some flexibility so that you can add more ports to a bridge in the future and it also keeps the address up even if the slaved physical interface goes down. Doesn’t a bridge interface use software as opposed to the switch chipset (i.e. more CPU)?

Let’s use the example of a wireless PtP link. Does it matter if my AP or Station is on an interface that is slaved to a bridge? OR should I just apply the address directly to the ‘wlan1’ interfaces?

Actually bridge adds more complexity so there should be a reason to make a bridge with only one port. But the performance effect could be barely noticeable.
