That is just more representation of the same sort. You exclude situations where the population is not at carryingcapacity, where the carryingcapacity does not apply. Again, you are excluding many things by bringing in all the requirements to apply selection, you are invalidating all sorts of biology, like looking at individuals, or looking at populations which are not at carryingcapacity.
It's even more curious that you do this because before you stated that fundamentally selection applies individually, and the standard formulation only includes variation because of the happenstance that there always is variation in a population. So it's not that you are suggesting these phenomena to be investigated separately from selection, you are in effect invalidating the investigation of the phenomena of populations which are not at carryingcapacity, and the relationship of individual organisms to the environment in terms of reproduction.
