I think the original intent was that bitbake.conf defines the basic PROVIDES/DEPENDS and then the recipes adjust as needed. As such, PROVIDES and DEPENDS would then always use +=. Unfortunately over the years this has gotten lost and bitbake.conf and base.bbclass had to become more inventive about how they set the defaults for the variables. As such, I think += actually makes sense but I realise that isn't the way most recipes work now. We could try and fix that but it does seem like a marginal gain when there are bigger issues.
