OK, waiting for input is a good reason.

If it still compiles, it's already a good start. But I think it's a bit unexpected if you can run tests but don't get any output anywhere in the default configuration.

Also, UART2 would be a better choice for a new BSP I think I would keep the USART3 active. I don't know how many users that BSP already has. But disabling or changing the console UART could be something unexpected on an update.
