Ну этим принципиально и отличается -- интерфейс на браузере. В гноме ещё некий закос под "нативность", а тут уже откровенно веб-параша, не стесняясь.

А какое ещё "принципиальное" отличие вы ожидали? Браузер уже сейчас -- операционная система, в нём можно что угодно запустить. Можно вообще на канвас рисовать из WebAssembly-кода. И что, тогда в браузере тоже от "веба" только интерфейс? Я думаю, что скорее стоит говорить в "новом вебе" от "старого" почти ничего нет. Огромный DOM со 100500 уровней вложенности; скрипты; на каждый чих; WebUSB, WebGPU, WebAssembly и остальная WebХрень, канвас, -- вот это вот всё уже максимально далеко от гипертекста.
