True but that’s not a carte blanche grandfather clause. For example with 5 they just did this with the humanization, a preference and a default of it off, expressly to prevent chaos with existing CC data. This makes a lot of sense given the investment in existing projects.
In this case we’re just talking about a tiny change in the user interface, hardly worth bothering about. And what about all the times they tweaked the interface in some way in the past, did all those get settings? Doubt it.
Anyhow we’re circling the drain here, I’ve dealt with this a million times in my career and if were me I’d not have a pref, and obviously they didn’t think it important enough or it would already be there, but opinions can differ. ‘nuff said.
