Interesting - I use these so routinely it's unconscious, never had a problem. Though I suppose if I'm doing something remotely risky I'll not use them - though I'm not aware of doing that. The class of shortcuts I love is: [command] !:1-$ which copies the arguments to the previous command to this one. Or: !:3 which copies the fourth argument. Once those were under my fingers my fellow architects were astounded.
