Yes, but my point is that most people who want to be using tpm2 emulation don't really care about QEMU ... it's a nice thing, sure, but it's very complex to set up, so it's only going to be the odd enthusiast that cares about vtpm in QEMU. Most people simply care about testing TPM2 code or playing with TPM2 itself and for that, they don't need or want virtualization. Could you not push tpm2 into the release branch with the caveat that the extremely esoteric BE on LE virtualization case doesn't work yet?
