Yeah, I was trying to work out what the actual differences are between
them and I suspect they're fairly minimal, but I don't know how we
should handle insertText:replacementRange: vs the current insertText:,
for example.

The new one takes a range and the old one doesn't. IMO it's none of
the window system's business where we insert the text, so do we just
ignore it? That might cause issues if we're dealing with the language
input stuff, so we might need to fiddle with that a bit (it was mostly
contributed by someone who actually used it).

I would agree that Apple's documentation is abysmal. AFAICT most new
features are exclusively documented in WWDC talks, so if you're not
immersed in the Apple eco-system it can be very hard to keep track of
what's changed. I assume that's some sort of marketing ploy.
