The shift from thin client to fat client forced the frontend to deal with greater state, sync and cache issues. The build ecosystem has multiple steps and langs. The visual fidelity and complexity of UI makes it difficult to test requiring us to deal with e2e testing with new tools.

All that to say this: we wanted cutting edge language features, beautiful UI and didnt want the page to flash white when we did something so we stopped switching pages and handled state on the front-end. Not sure it was all worth it tbh.
