FWIW, the crying rancor keeper is one of my favourite moments. It’s the most creative moment in the whole Jabba sequence, IMO. It adds a bit of depth to the world, and it’s just plain hilarious.
I can understand why it’s polarising, but my vote is for keeping it. I also love the ironing droid in TLJ, so maybe I just have a thing for bathos.
I like the rancor keeper too. Made me laugh when I first saw it as a kid.
