mysqldump --system=users might be better with CREATE USER IF NOT EXISTS

This is the command I'm using:
mysqldump --system=users

Can you evaluate whether including IF NOT EXISTS on the CREATE USER statements might be better?

I learned I can use the "-f" option on mysql command to workaround the problem which allows it to skip the errors.

Thought I'd share this since I was stuck and confused about how to do it for a while.
