I'd say that if the receptacle was able to hold the drippings, then it performed its job and you shouldn't worry about it. As long as you don't get drippings all over the place, then you shouldn't be concerned.
My process is to always wipe clean any oil that I see in that receptacle, plus the filter gasket mating surface, before installing the new filter. Also, I rub clean oil on the new filter's gasket before screwing the filter in place. I tighten the filter as much as I can by hand, plus 1/4-turn more with a filter wrench.
