a block cleaner can be accomplished much easier, and there are plenty of ways to do so:
Indeed, that is very true, but I might have not really made clear why we should bother with more complicated clean-up. As it stands, every crawler can only carry on with spark from active cells, which happily include gliders. So as far as the input goes, at least 1 glider is needed. Now the question is can we have a subunit of some kind that produces more gliders than it consumes, so far there are some ways, but one need specific still life configurations that are unclear how to obtain. Now, suppose you succeeded, but debris remains, then you need more gliders to clean, so that unit is not working as advertised. The crawler has a puny weak spark, and leave a block, so one can only break even using it. The much larger spark of that "clean fuse" could clear much more blocks than a simple glider can (in some configurations), and maybe some interactions can yield additional gliders.
As long as we do not have a way to produce more gliders than consumed, any crawler-puffer that manages so retain a period of 41 is worth mentioning at this point (I think), and this one is "clean", so I think we just should have it in mind.
