It would appear that Solus does not have a TPM2 implementation, so this may fit the bill.
Additionally, one of its components (tss2-esys) is now required in order to compile fwupd, so this could resolve one of it's blockers before it even becomes a blocker.

Potential users for this software stack: Anyone who requires TPM2, and in the future, anyone relying on fwupd (and it's dependents, of course).
