[2022] Isn't it high time to get rid of the Fake Japanese vehicles?

No, you simply ignored official answer.

Interesting fragment marked bold and underline.

There is a general lack of information connecting the T-1 to any meaningful / useful loadouts that would make it worthwhile in game. Additionally from an air-to-air perspective, Sidewinder claims aside, a single 12.7mm machine gun is not much use as a fighter or attacker in most capacities. Especially since the thing in question here that it would theoretically be replacing has a battery of 4 x 30mm cannon.

If more information about useful payloads and weaponry options come forward, then it could remain a possible addition to the game in some form. But right now its not being considered.

Generally apart from the few images already shared, there is lack of info thats required to implement the vehicle. Nothing so far has been worthwhile perusing in this area. Naturally people are welcome to submit topics with material if they have it.

Under the same rules on which the KT 105 and Panther II were removed, neither have any variant that is really one that would be added again in the current context. Ho-Ri is perhaps a little more solid, but much is still in question on the tank.
