When is VRT going to be utilized?

Hello, I am new to Venus and I LOVE the platform!

I am wondering when VRT will be utilized in the platform. I have the v token in my metamask but I am wondering what it will be good for and when I can use it in Venus. It looks like I can trade it away on a swap platform but I dont want to do that until I know how useful/valuable it will be.

I have a small VAI loan. Can I use VRT to pay down my VAI loan?
Can I soon use VRT as collateral?

From what I have read it sounds like we will be receiving VRT instead of XVS when borrowing and lending. Is that right?

Anyone know how soon these changes will be happening?

Thanks!
