This change appears to have happened around September 2021. I could not find any official announcement, but I could have missed it.

This just cost me fiveten minutes of my life (only because I have gotten used to it, having been broken multiple times now from main branch renames in various projects).

I am here to complain and perhaps save some time for anyone else who contributes to Org mode or uses the source occasionally.

If you're still tracking master, you're missing commits.
