Does it matter? Because developers are actively working on testnet4, and discussing the network reset:
https://groups.google.com/g/bitcoindev/c/9bL00vRj7OUWhich means, that even if some faucets are working right now, they could become worthless, if the network would be resetted.

Also, v3 Testnet wouldn't just stop working suddenly.
Finally, v4 Testnet would be easily able to obtain I'd imagine...
People need to be testing, learning, and building.
