My question on every announcement of an invention of a new web framework is:
- How do you add a database to it?
- How do you add passwords or secrets?
- How do you boot in dev vs test vs prod?
- How do you test it on many levels?
- How can I upgrade it over time?
- How can I learn how it changes over time?
- How can I opt-in to future features?
These and other things is what takes many years to "finish" a framework.
