I didn't say "if your music player inhibited suspend" I said "if your music allowed you to inhibit suspend." The implication is of course that there would be a checkbox in preferences that would let you manage the behavior.
Generally laptops have thermal cutouts so I'm not sure what this firehazard stuff is a bit silly.
I would prefer to have customizable (yes hahaha this is Gnome, they don't do customizable) automatic suspend behavior over having to manually suspend it myself or having it automatically suspend whenever I close the lid.
Perhaps some sort of global "inhibit suspend" option in the power management applet would accomplish this in a more obvious way than making it a per-app configurable.
