I think that juniper learnt from Cisco's mistakes while Cisco is stuck with their config command structure as they decided to chase backward compatibility and familiarity across products.

I’ve taken entire systems offline because of unexpected command expansion.

My “favourite” was “admin”, which was used as the login user, was also short form for “administer-all-port-shutdown” (or words to that effect; it was a long time ago). So if you were distracted when logging in, you could easily soft-lock the entire device meaning you’d have to then run into the DC, find the hardware, and physically power cycle it.

Absolute madness.
