I stopped working with ember about a year and a half ago and it's interesting to see how major progress seems to have halted. It became pretty obviously hindered even before then with the controllers to routable components initiative, but I can't seem to . I don't check in on it often enough to be an expert in the project now, but I get a feeling that the new glimmer stuff is a similarly distracting big idea that will get in the way of many smaller improvements that could go out in that time.<p>That said I do still sometimes miss ember, specifically ember data. I was pretty hesitant to start using using ember with all of it's magic, but having all of that magic really felt like it kept us from over thinking most small problems we had to solve. Also the codebase was extremely easy to digest, so things that seemed like the framework was standing in the way of usually only required an hour of poking through the library code and you could build out functionality you needed with private APIs. Got really familiar with the data codebase and got to pull off some fun hacks.
