Did it even fall out of fashion?
I thought Batman being a raging hardcase who emotionally traumatizes or physically abuses his protege's or family while also being abrasive, distrusting, and cold to his fellow heroes was still the general rule when it came to writing him .
I wouldn't just assume it's from Redondo if only because it's how Taylor's written Batman in other books.
I hated that line in one of the last issues from Babs where she basically blamed Dicks' inability to let himself be happy on Bruce or his "programming." Like all their emotional problems are because of Bruce.
