Why are we removing these? Now users will have to also do reflex db init before the app can be used.

Why are we removing these? Now users will have to also do reflex db init before the app can be used.

Isn't it more confusing to get an error like this when first downloading reflex, picking a template and doing reflex run?

(Background on this error at: https://sqlalche.me/e/20/e3q8)

There is an warning message Target database is not up to date. Run reflex db migrate to update database.

But in a first install would be easily over looked. Then when they up the app and get the error message from above its not really clear how to resolve it

[Alek99]

Should we cut the command at the red message instead of continuing to run?
