That's not what I meant to say at all. Here, I saw what looked like a new project. You say I should have understood right away because Glimmer is said to power Ember's components. But the Ember team could very well have built an entirely new engine for its components. I thought Ember used to use Handlebars (didn't it?) and had just recently built a new engine (aka Glimmer) instead of adapting an existing one (React, Vue, etc). But that sounded odd, hence my question. If you see these sorts of things all the time, there may be a reason: communication is hard and we all interpret things a bit differently (depending on our experience, our mindset, our native language, etc).
