I think that most wanting to use Deno are wanting to write an application in a more Deno friendly way. Linting, formating, and typescript in the box. But pragmatically also needing or desiring to be able to utilize existing NPM modules. Those NPM modules more often than not needing node compatibility.

It doesn't mean the application at its core will be more node based so much as wanting to be able to use a given NPM module.
