Just one hint if you are using Trezor Suite application, you can enable experimental feature Early Access Program and receive this updates early for testing.
You can leave this program anytime if you no longer want priority access to new features.
I don't think taproot is well used at the moment and I think it was satoshi labs that were trying to make their own coinjoin/privacy based service too so those are both very proactive improvements that might not be used yet but will have been around for so long when they are that they'll have the added security of that (if the code is older, there's likely more people to have seen it and audited it).
You couldn't be more wrong about Taproot usage... it has been used more than ever and I have chart to prove that.
Now that may be for silly reasons of using ordinals, putting rocks, stones and monkey images on bitcoin blockchain, but it is what it is.
It's going to be used much more in future for real stuff after this hype wave is gone.
