this sounds less than optimal as it seems to lead to the next workflow

• There is a JS error. It is hard to trace where it comes from
• change your wp config, set debug_scripts to true
• recreate the error to be able to pinpoint where it comes from
• solve the bug
• change your wp config, remove debug_scripts setting

I would go for something less conditional like show it only to admins (I am assuming all developers have or can safely be given admin role, not sure how much this assumption is true in real life)
