Ah, great, no worries then. Just wanted to make sure you had an explanation.

There are a few other cases to consider. One is with packages that are
tweaked without forking the packages. For example if you were to
upgrade gstreamer you'd lose our pulseaudio tweak that makes sound
work, and if you upgrade firefox you'd lose the tweak that makes it
use totem for video playback (totem uses hw accel and works well, ff
internal one doesn't use accel and performs badly).
