Qualcomm does have similar architecture deployed, here is their hypervisor: https://github.com/quic/gunyah-hypervisor.

AFAIK Qualcomm's implementation does include passing touch input / display into the VM and is marketed in similar term ("Trusted User Interface") to TEE-based techs, except they are not in S-EL0/1.

I've only seen this used in some really obscure scenario (cryptocurrency wallet) though.
