I’m posting this here because there is no post for this in the #grammar-points forum
I’ve noticed the general pattern を～に（して）for numerous grammar points, so I was surprised to see that をよそに is documented only in this reduced form. Some quick searches turned up a few real world examples of をよそにして. Is its exclusion from the grammar point description perhaps just an oversight? Searches for をよそとして came back null, so it seems indeed that is not used–at least not in anything crawled by Google.
(By the way, I’m aware the reduced form is far more common, I’m only asking for the sake of completeness.)
