I don't mind if it's not a well-formed plist myself, if the last element
is always the query. It saves some typing.
On that note, I'd probably prefer it if we had something like this:
(treesit-font-lock-rules
'(;; To avoid repetitive typing:
(:default t
:language 'python
:override t)
(:feature 'string
'((string :anchor "\"" @python--treesit-fontify-string)
(string) @contextual))
(:feature 'string-interpolation
'((interpolation (identifier) @font-lock-variable-name-face))))))
