A couple of months ago I started listening to the Scriptnotes podcast, by Craig Mazin (showrunner for Chernobyl and Last of Us, also wrote for Scary Movie and Hangover sequels) and John August (Go, Charlie's Angels, Big Fish, etc.). They discussed receiving notes like that from executives on their scripts- that there needed to be a line of dialog here to explain, rather than just using the visual to explain, so that someone on their phone could follow along.

There are, of course, ways that writers and directors get to ignore executive feedback, have a bunch of recent hits already is one, do your movie outside the studio system is another, have it in your contract because you gave up some money or whatever is a third. This is why some movies are still made in older ways, but from what they said that feedback is pretty universal now.
