No one would want to build applications for a platform that lacks widgets capable of properly displaying, formatting, and editing text.
Is the idea that people are only going to be running Iced applications in COSMIC? It feels to me like the realistic option would be that, if COSMIC ever becomes daily-drivable, people would still be using GTK applications with it, at least at first. Might as well use a GTK text editor then? Then System76 could focus on building a text editor after COSMIC is a thing, and COSMIC would hopefully arrive sooner (or even at all - this looks like the path to burnout).
