Don't worry, at the speed at which IRCv3 is being implemented we won't see the effects on real-world servers for another 20 years anyway :P

I know I exaggerate but I'm sure that traditional IRC clients will be supported for a long time to come as a fallback.

Personally I'd like some mod cons, like the server keeping state and not needing a bouncer. Server side scrollback would be another one.

However I'm not sure if these are in the standard. Not a fan of the typing indicator either.
