Performance matters a lot, because program can autosave in quick sessions after simple steps. Even more important if multiple images are edited or loaded. While this is not the biggest improvement, it is still something to keep in mind. Performance should always be a priority. Programs will keep expanding and add bloat over time, so its good to have a format like that in mind.

You should always measure first before blindly following dogmas. I doubt that the choice of serialization format is what dominates processor time in this case.

Then you follow it by doubting it without measuring:

Also note I was not just speaking of today, but with future additions and changes. You can't measure the future, but you can plan ahead and build upon a good foundation, that the small format can be used for extending it in future. That's the idea. Also to test what you suggest they have to build the entire system years and waste lot of time and effort.
