That house style is going the way of the the Oxford comma, the possessive gerund, and the compound hyphenate. It's been happening for awhile now, in no small part because the style is suboptimal for search and social.
I love Oxford commas. It's an unhealthy love, if I'm being honest. They'll come for my commas, eventually, those descriptivists will. When they do, they can pry my Oxford commas from my cold, dead hands.
