Some added context: MIDI 2.0 is still not that widely supported (in hosts, plugins, etc). It's also not present in 99% of currently on the market hardware synths and music controllers etc you can buy, and it's available in 0% of older hardware.

There's also MPE which adds some more expressive capabilities to existing MIDI hosts, plugins, and hardware, which has some (small still) adoption. MPE is an extension to MIDI 1.0 to add polyphonic expressivity, and a lot of companies have added it in an ad-hoc fashion (what it offers is within the bounds of MIDI 1.0 "extended" modes).

So, unless you're living in the cutting edge, MIDI 2.0 will not be of much use for modern music production for the next few years at least.
