Ditto, having consistent and useful text-editing keybindings in ~all fields (that use the native toolkit, at least) was something I didn't know I needed until I experienced it. Anything that's (even) less consistent than the real-world experience of that on MacOS feels... wrong, now.

I use this feature frequently too, but the downside is that it makes non-native textboxes stick out like sore thumbs because they don't implement it.

In fact, this is common to a lot of little poweruser features on macOS, and I think is a big driver of distaste towards non-native apps by long-time Mac users.
