I don't object, in fact I encourage it. I've never, here or elsewhere, had anyone do that to the point that it was a problem. By not broadcasting it no one has to wonder why Swapper A chose to send those precious seeds to a specific person, especially if more than one person has expressed interest in the same seeds. And when hosting, I would much rather it be slipped in without a lot of fanfare than start a back and forth of negotiations outside the perimeter of the swap, creating a bunch of little side swaps that the host is expected to be responsible for processing. I do try to count the packs to make sure they match the total number on the list, and spot check here and there, but if I encounter a bundle with more than the expected number of seeds and the extra pack(s) are marked "For Swapper A" it is not a problem.
