[Changelog for version 10.17 of a piece of software.]

One change listed: “The CPU no longer overheats when you hold down the spacebar”
Comments: LongtimeUser4 writes: This update broke my workflow! My control key is hard to reach, so I hold spacebar instead, and I configured Emacs to interpret a rapid temperature rise as “control”.
Admin writes: That’s horrifying.
LongtimeUser4 writes: Look, my setup works for me. Just add an option to reenable spacebar heating.

Every change breaks someone’s workflow.
