Mostly agreed... I think of deno more as an alternative major change (much like python 2/3 split). Not sure if deno will take over, there are a lot of places that should be shorn up... one of the big ones for me is a consistent ffi library, and while node-ffi package works, it's not exactly transparent and imo should be in the box.
Deno is pretty solid in most other areas though... only native modules need a bit more considerations for the use cases without a good alternative. That's a little outside my comfort zone as a developer, but there's work in progress for all of this.
