What difference does the runtime make to the (average) end user? I love that I can create shortcuts of some web apps that have their own window, menu bar etc. (this is already possible in Chrome) and I don't really care they are "web" apps.
That has nothing to do with the runtime, rather with the implementation. Barrier to entry of web development is low so average quality is also low. On the opposite side of the spectrum you have products like Figma, Notion, Google apps etc.
