The thing about the thumbs up is that removing it helps a later change about Han needing a “clean ship.” The lighter joke is still there!
I thought the idea was that Han could take them there but he just doesn’t want to get too involved, which is why Maz refuses to help him. That’s why the pointless “clean ship” line could be removed with no other changes.
This has always been my interpretation too. I don’t want to sound like I’m Testing anybody’s patience by saying that though; the point of fanediting is to alter things to be interpreted differently.
