In fact, he has written an article about that sort of thing, which you
can find linked here, along with some other destructuring tools:
https://github.com/alphapapa/emacs-package-dev-handbook#a-callable-plist-data-structure-for-emacs
https://github.com/alphapapa/emacs-package-dev-handbook#with-dict-with-plist-vals-1
Note that automatically binding variables named according to plist keys
which are not known in advance would have to happen at runtime and would
require use of eval, as well as potentially overriding variables that
you're already using.
Instead, I recommend using -let, which has a &plist keyword, which you
can use like:
(-let* (((&plist :query :preamble :preamble-case-fold)
(org-ql--query-preamble query)))
(list query preamble preamble-case-fold))
