There is no safeguard. It’s just that first only has single syncros because people don’t typically downshift into first. If you learn how to double clutch you can slip it into 1st with literally zero resistance. Keep in mind that double clutching is not the same thing as a typical rev match.

Clutch in
Pull to neutral
Clutch out

Clutch in
Pull into first
Clutch out

The key is matching revs while in neutral while the clutch is out. A typical rev match would be done while the clutch is pressed so all you are slinging is the flywheel. Blipping in neutral with the clutch out will sling the flywheel AND the input shaft. Doing this dramatically reduces the load on the syncros.
