The original document read like the worst kind of homebrew. Even after revision it has serious problems.
1) The versatility is obscene. Nobody wants to play in a party with someone who is good at everything. Kind of defeats the purpose of the party based adventuring that d&d is designed for.
2) The Psi point system is poorly implemented. Having the spell points of a full caster but with enhanced flexibility is a significant power boost over other classes.
3) The covert nature of psionics is overpowered. Subtle spell costs sorcery points. The mystic can do this without cost.

Honestly thought all this was common knowledge.
Your proof that they abandoned it is..?

Just because in your opinion something is too versatile doesn't make that thing so good it's broken. Pretty much everything a Mystic can do can be replicated or exceeded by another class.

The Psi point system was fine, it made the player balance using their abilities throughout a day and flexing enough to get things done, it's extremely easy to burn through your points with encounters left in the day.

Psionics also didn't go beyond 5th level spells in power, it was meant to be different to casting and in the Mystic they achieved that. It was just UA so the supporting rules around Psionics was a bit thin but that's hardly the fault of the class.

Have you played or seen a Mystic in play, or are you just repeating opinions regularly voiced? I've seen criticism on the Mystic many times so in that sense, sure it's common knowledge. But I've never seen any real substantial back up of those claims. If something isn't to your taste that's one thing, but it's hardly broken.
