I also removed the last traces of EmberJS from our apps last year. It was a great feeling.
Ember was fun and productive initially, but eventually turned into a quagmire when the app got larger. Seems like most people I knew in the community have moved on too.
I just built a site using Laravel & Vue glued together with Inertia. It was a really nice experience!
Nice reminder that killing your darlings is needed more often than not!
