On the frontpage of Endcrawl, the company behind this blog post:
> Ace your end credits and de-stress post production with the solution used by over 2,000 films and series.
Having a standard template seems like a way to easily "de-stress post production", and maybe even "ace your end credits". If this actually becomes an industry standard, the company behind it would also get some publicity. I've personally never even thought about how credits were made, and never knew that there were companies focused on just this point. Now I know that Endcrawl exist, and have a positive opinion of them because they wrote an intersting blog post, that could be used as a reference for other ordering problems. They're also trading this standard template for your email address: https://endcrawl.com/template/
Probably not. They do credits for movies of all sizes. If you're doing a small student film, do you really want to think about the order of your credits? This gives you a great default choice.
