Hi,
I just wanted to share that the Open Source Security Foundation (OSSF, [1]) has recently developed a tool called the Open Source Project Criticality Score (Beta) [2].
As of December 24, 2020, OP-TEE OS is number 39 in the top 200 C language projects on GitHub, ranked by criticality score. Not bad I think.
