Is that a real difference, or is this a "toast in a freezer" kind of thing where the difference between freezer and countertop temperature is so miniscule compared to the toaster heat that it doesn't make much difference?
Thermal expansion was why the o-ring failed for Shuttle Columbus, and that was due to a snap freeze in florida. So i guess if they accounted for it? But still, having things be *colder* than they will be means a lot of thermal expansion calculations. Hell the SR71 basically leaked gas on the runway to prep for being anywhere and so when it was top speed it had room for thermal expansion.

Also, warm. Cold isn’t good for a thing that’s about to be REALLY hot from friction. See: Columbus
