Interesting suggestions, AN-A.
I can't find rebundled, or for that matter, rebundle, in a dictionary either. But I agree it's in wide use, and with meanings that are usually obvious in the context. Often it relates to new business models or technologies. For example, splitting up the electricity supply industry into separate functions, run by separate companies was often called unbundling. (And unbundle is a Chi word.) When some of those companies start swallowing each other up, it might well be described as rebundling. And similar processes can apply to media content, financial services, etc.
So, it's probably just a matter of time before rebundle does appear in dictionaries. I'm in two minds about whether we should anticipate that development in the Chi word list. It's not an urgent issue as far as rebundled is concerned, since today was its big chance to be an extra nine-letter word, and it's missed out on that. But I think rebundle and rebundled should be added to the list, and maybe the former will pop up in a puzzle some time.
I can find shitter in some dictionaries. The Shorter Oxford says it means "a person who or thing which shits" or "a privy, a lavatory; a lavatory pan". I think it should go in our list for future puzzles.
The reason hotties is not allowed is because the singular (whether meaning a sexually attractive person or a hot water bottle) is written hottie rather than hotty. In saying that, I'm giving away a word that can be played (hence the "spoiler" heading), but I'm probably not giving away much, since most experienced players, on having a "...S" word rejected, will immediately try it with the S dropped off.
