well i like that they aren't unconditionally sending the telemetry remotely
# Collect information and statistics about the current build, and write it to
# disk. Enabling this has no impact on the resulting build output. The
# schema of the file generated by the build metrics feature is unstable, and
# this is not intended to be used during local development.
#build.metrics = false
although the unconditional bootstrap downloads are a form of telemetry already
