Ok. How about a separate parameter that just returns kungetct?

My use case is disabling zsh-autosuggestions (https://github.com/zsh-
users/zsh-autosuggestions)
while bracketed-paste-magic and other
widgets using zle -U are running. Ideally, I could just avoid fetching
a suggestion until $PENDING and this new param are zero.
