Receivers know the selector. If they feed domain and selector into their Bayesian processors and get a useful distinction, they are going to use it. No RFC will change that. If there's some statistically significant difference in 'sources' identified that way, then that's their call.Agreed 100%
This was a hot topic when DKIM first came out. It represents a failure to use or understand the role of selectors properly. The reputation /should/ rely only on the domain name /without/ the selector, so the selector can be used only for administrative purposes, such as rolling over to a new key.
Note, for example, that including the selector in the reputation analysis means that the history of the actor is lost when a new selector is used.
