It's quite likely that many spaceships that have tag-alongs (whether true ones like the Canada Goose, or fake ones like the Fireship that actually alter the ship itself), may have ways to r...

I am assuming Gs means Gliders - if so, does a Herschel also qualify, or no ?
I would think of a Herschel a bit more like a Uranium atom - it emits a few useful energy quanta (gliders/neutrons) but leaves behind a bunch of inconvenient junk.
