So we shouldn't:
- Use source control?
- Have build automation?
- (at least some) automated testing?
- Protect data structures accessed concurrently with a mutex?
- Have backups?
I wouldn't say there isn't some imaginary situation where you'd do something different, but it's safer to fall back to doing the above in most situations.
That said many people make up "best practices" or use them without understanding the circumstances to which they apply.
