Happy to announce that I'm working on modernized Intel firmware toolig under an OSFF grant, I am starting with a rework of what me_cleaner does:
I am currently taking a closer look at what me_cleaner as of its latest commit is doing, and what people suggested through PRs - which quite doubles the feature set.
There are attempts to support newer platforms, with certain drawbacks (as expected) since the ME is a core part of the platform design and boot process. E.g., it would break S0iX.
Feel free to create issues to this new repo.
