You could argue whether or not it's a "feature", but one of the thing ghostty claims as an advantage is the out of the box configuration.

With no config at all, ghostty looks nicer than my alacritty setup. The rendering is just real nice. I could probably get alacritty to look as nice or nicer, but ghostty just worked this way with no config needed.

So you could consider aesthetics and rendering quality, and simplicity of setup both as features, which people may need/want (or not).
