I don’t, I think some others may have experimented with it as well as an attempt to format/highlight in Cursive. I’ve personally just used newlines for new conditions and Cider indents that well enough that it hasn’t bothered me.

Is there something in particular that looks strange to you?

the default indentation looks like this:

(defrule rule->legacy-contract?
  "Add a Legacy fact into the session if the contract was sent with this status."
  [?contract <- Contract [ct] (= ?principal-external-id (:contract/principal-external-id ct))
   (= :legacy (:contract/status ct))]
  =>
  (insert! (->Legacy ?principal-external-id)))

and I have to manually change it to:

(defrule rule->legacy-contract?
  "Add a Legacy fact into the session if the contract was sent with this status."
  [?contract <- Contract [ct] (= ?principal-external-id (:contract/principal-external-id ct))
                              (= :legacy (:contract/status ct))]
  =>
  (insert! (->Legacy ?principal-external-id)))

sometimes I need to use M-x align-regexp (= to align the conditions
