My understanding was that the goal for Glimmer was that people shouldn't need to use all of Ember, instead they could also opt for only lightweight Glimmer components (maybe as a part of a bigger app).

Somewhat related, there is a new project from the Snowpack crew/company, where the intent is to make a tool for rendering (mostly) vanilla HTML/CSS/JS out of JS frameworks.

Seems like their goal has some overlap with that of Glimmer. Maybe it would be a better idea to rely on their project for heavy work, and only prove the thin translation layer (renderer) for Glimmer/Ember.

Just wanted to put the idea out there. Don't know if this is a good idea or not.
