What's scary about it? It's the bootloader telling you it's in dev mode and not checking signatures.
And yes it sits there for 30 seconds. Ctrl-d boots immediately from internal storage and Ctrl-u from USB or SD.
I'm not sure why you need to wipe when switching between dev and recovery mode. Maybe it's to stop you booting an alternate OS and getting at ChromeOS user data without a password?
