I have always fed in a plastic container outside of the enclosure because my snake will roll her wet frozen thawed rat around and if It were in her enclosure (eco earth substrate) it would look like someone covered a desert in Oreo and chocolate. She also has an amazing feeding response and doesn't care whatsoever even if with an audience. I say if it has always worked and your snake is fine with it than no need to switch methods which could cause stress too. This is just my snake and my positive experience though and is not always true for everyone.
