It was pretty straightforward (although tedious) to write custom CSV data exports in embedded C, with ZERO dependencies.
I know, I know, only old boomers care about removing pip from their code dev process, but, I'm an old boomer, so it was a great feature for me.
Straight out of libc I was able to dump data in real-time, that everyone on the latest malware OSes was able to import and analyze.
CSV is awesome!
