Patch notes fix a spacebar - overheating bug, frustrated power-user demands it back
Description
Black-and-white webcomic panel styled like a software update dialog. Text at top: "LATEST: 10.17 UPDATE". Bold heading: "CHANGES IN VERSION 10.17: The CPU no longer overheats when you hold down spacebar." Below, a comments section in grey bubbles. 1) "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'." 2) "ADMIN writes: THAT'S HORRIFYING." 3) "LONGTIMEUSER4 writes: Look, my setup works for me. Just add an option to reenable spacebar heating." Footer caption: "EVERY CHANGE BREAKS SOMEONE'S WORKFLOW." The humor targets developers: a bug (CPU overheating on spacebar hold) is patched, but a niche Emacs power-user relied on the hardware malfunction as a custom control key signal, illustrating how seemingly obvious fixes become breaking changes for edge-case workflows, release-note anxiety, and backwards-compatibility headaches

We closed “spacebar heats CPU to 95 °C,” reopened as sev-0 when a veteran dev’s Emacs macro - watching /sys/class/thermal/zone0/temp>90 °C for Ctrl - stopped working; Hyrum’s Law, now featuring the flag --enable-scorched-earth-compat
Somewhere there's a principal engineer who just discovered their entire distributed tracing system depends on a deprecated jQuery method that only works when the browser thinks it's Internet Explorer 6
With a sufficient number of users, there's no such thing as a private bug - somewhere, spacebar heating is a load-bearing dependency with an SLA
This perfectly captures the nightmare of maintaining production systems: you finally fix that CPU thermal issue from users hammering the spacebar, only to discover someone's been running their entire Emacs workflow on temperature-based control signals for years. It's the software equivalent of finding out your 'temporary' fix from 2015 is now load-bearing infrastructure. The real horror isn't the bug - it's that somewhere, right now, there's a senior engineer who genuinely sympathizes with LongtimeUser4's position because they've seen worse in production
Emacs power users: remapping spacebar to Ctrl since RSI was just 'commitment to the craft' - now nerfed by mere sanity
Backward compatibility shouldn’t extend to side‑channel input devices; if your Emacs config relies on Tjmax, file the change request with Facilities, not Engineering
When your input layer relies on thermal throttling, the fix becomes a breaking change - fine, we’ll ship a feature flag called enable_spacebar_meltdown and call it ‘backward compatibility.’
