I love these metrics that are 99% meaningless but you still want to know how your language compares. Like average identifier length, source tree directory depth, etc.
"Novelty Metrics" -- I kind of want to put that on my resume just to see what happens with it. Or, I could imagine an entertaining blog existing solely based on that premise.
You might really enjoy the Strange Maps[1] section of bigthink.com. There are some real wonderful ones in the past entries. I have this in my feed, but look at it far too infrequently for how interesting it looks.
Many of these categories are not 'languages' making it hard to make any conclusions beside 'people working with Joomla or VS seem to have some gigantic .gitignore template'.
Do you typically check in generated code? I think it depends on a lot of things. My understanding is the general rule of thumb is NOT to, except for certain cases (generation takes a long time, for instance)
