For more fun, try putting a "--" (two consecutive hyphens) in many fields in the AWS console. Not allowed, I guess because they're passing it to shell commands somewhere along the line?!

Not likely. That's the comment start marker in many dialects of SQL.

For commands, shell metacharacters like `, |, &, and $() are much more important.
