    For example, from the commit deleting the author_is_elon feature, I don't see a deletion of any config files. It may very well have been the case that the author_is_elon feature was never used for serving production traffic, being ignored by a config value. Maybe they need predicates like this in order to capture metrics. So if someone asks "are we showing more tweets from Democrats than Republicans?" they might need to define author_is_democrat and author_is_republican predicates to measure whether there is a discrepancy, controlling for various other factors. The mere existence of those features does not indicate anything nefarious.
