It's the only compact C-only example that I'm aware of that shows how to put together the basics of an SGX user space. Here a more permissive licensing would make sense in my opinion just to give a seed for alternatives. Right now the user space implementations are either in C++ and Rust, and they work great for big things like containers etc. I could envision someone to have something more minimalistic to do something simple for lets say a system daemon. I've done a similar decision with tools/testing/selftests/tpm2/tpm2.py in the past. What do you think? /Jarkko
