This thing isn't really complicated, because all the hard-lifting is done by the design of TPM, not even TPM chips. Measurements and integrity checks are proven to be mundane tasks, and, for security, it's a good thing. Even without systemd, one can learn and integrate TPM in one or two months. But the systemd team has been working on this like 2 years now. I'm quite curious what they've been doing. Security audits, maybe? Preparations for other integrations? I'm not criticizing here - I've been away from that scene for an year, and I wonder if there have been some new interesting developments or ideas that I'm not aware of.
