Right now, somewhere in the bowels of booking.com, a middle manager is crafting an e-mail to the front-end devs, "hey can we remove that .persuation-msg CSS class, and replace it with those nonsensical .xj892FXy0-style class names that are all the rage now? Thanks!"
Please tell me you're aware that those "non-sensical" classnames are machine generated during a production build? An eng isn't manually choosing that name.
