Will the server ever update to 1.10 or 1.11 only?

I'm pretty sure it's possible to not use the good PvP that comes in with 1.9. And if so, why not just update it so you can get new blocks and mobs (Polar bears...)

Minecraft will be version 1.16 and everyone will still have 1.8 like wtf

And I know 1.11 isn't out yet...
