We're nowhere near the point at which sample player velocity needs or could even benefit from MIDI 2 resolution. Unless of course you happen to have some exotic and very high-price machinery with several TeraBytes of RAM, several dozens of TB of storage, and a very large number of CPU cores that could qualify as an entry-level Supercomputer! And all that's assuming you'll be able to find sample libraries that target such machinery. In short, I'd suggest you don't hold your breath.
Also, using MIDI 2 to enhance the scope and scale of software instrument plugin preset selection and control - already absurdly overdone by developers in that merciless market - is unlikely to be enthusiastically received by seasoned (and jaded) users; more likely by the "more-is-better" and "latest-is-always-greatest" brigades of noobs, bluffers and con-artists.
Even at the specification level it's clear that MIDI 2 has its virtues and it's certainly not short of vices; but these won't be obvious to most folks in the user domain ahead of the few truly talented designers who'll take us all nicely into tomorrow in their own inimitable ways and in their own good time.
Oh but meanwhile, there's always Elon & co who like to pepper their products with what seem to be innovations (but mostly aren't), because hey - how else can they justify their churlishly high prices, keep their cult followers feverishly excited, and bask in all that public adulation? Lol.
