That is also how Krita stores brushes. Unfortunately, that can cause some unexpected issues when there's too much data [1][2].

If a patch is needed for libpng to get around the issue, maybe Krita should vendor libpng for usability. It's not unreasonable for people to want to create gigantic files like this.
