They don't include command line arguments (yet). They include the command verb (dotnet [build/restore/etc]) that was ran.
What happens if you accidentally paste an AWS secret key or similar in the middle of a command verb? Will that too appear in public csv files a year later?
> Only known arguments and options will be collected (not arbitrary strings).
We don't want your AWS secret key in this data as much as you do. We have put systematic mitigations in place to ensure that this doesn't happen.
