Just want to bump this post to re-share Brent's blog link (thank you Brent, and thank you since-banned anonymous user who posted it!) for anyone else who craves reliable information. The blog doesn't seem to be active, but it's got a decade's-worth of archived posts. Ah! So glad to have found it. Had no idea.
