You can't say something is mature enough when it's been activated only few weeks ago.
Maybe you have some top secret information I don't know, so please tell me what wallets could be used with Taproot few years ago in bitcoin mainnet?
I'm talking about the algorithm not the implementation. Taproot as a proposal and the algorithm has been discussed, reviewed and tested for a very long time. It activated on private networks then Signet then Testnet and when it finished maturing it was activated on MainNet. That is how every change should be since immature changes lead to vulnerabilities in protocol.
