Highly debatable, depends on the yeast. Some yeast are so aggressive if there isn't enough food/nutes to go around they will try to feed on themselves, and this of course will add for unwanted off flavors.
As I said, in theory. And there's gotta be some good reasons why way overpitching is not common practice, more than likely including yours. But an extra teaspoon in a gallon shouldn't cause that much political strife among the yeast population, when you consider the lees from a good batch is probably a hundred times that volume in dead yeast
I agree about the stainless but I'm still beer paranoid and even keep stainless exclusive for brewing. Its overkill but I can't not do it!
I won't disagree, it's a good idea... even my stainless jam and jelly stuff isn't allowed near the regular cooking implements, although it's more for fear of abuse than contamination... "If it can't handle the way I cook, it shouldn't be in the kitchen," says my husband... so the stuff I don't want him breaking is hidden.
