Even tho still only "compile-tested" code the from_slice implementation in TpmList and associated iterator is enough evidence that the approach is in fact effective:

And once the disease is spread fully, "parse" and "build" become unnecessary. Bytes are the type and "build" is `as_slice`. Most likely 0.11 size will shrink from the current 8K line to something like 5K once all of this is done. It's a pretty decent number taking into account that the care is fully self-contained with no external dependencies.

This makes me think what's really the point of using "higher level" framework like TSS2 after one has more idiomatic and easier access to the actual core architectural type ... It's pretty quick to build resource managers and stuff like that on need and per application after you have such a tool.

In some ways this does rise an existential challenge to pre-existing sofware stacks, at least to the level that I personally rather build more software around this core than have focus on getting tpm2-protocol integrated anywhere really. I have MockTPM in good progress and some pieces for tpm2-policy module. I guess you can call that an "SDK" or something.
