The game has two word lists -- a "possible solution" set and an "allowed guess" set. They removed:
* some words with negative connotations from the solution set
* slurs from the allowed guess set
As such, I believe there already weren't any slurs in the possible solution set. Or at least they weren't in the group of words which were mentioned as removed here. So, your scenario was already not possible.
I think removing the words with negative connotations from the solution set was a great move because, while they aren't slurs, there's no need to give people that negative experience.
