This "nursery GC" variation would be very similar to these "pre-mempool" / = "memswamp" proposals, as well: * https://github.com/bitcoin/bitcoin/issues/14895#issuecomment-665975441 * https://github.com/bitcoin/bitcoin/issues/14895#issuecomment-666267749 It may be better to continue thinking along those lines than to consider th= is GC concept.
