Does the Unpause button have a CAPTCHA, because it's only a matter of time when software will try to auto-unpause if there's a failure... and the cycle repeats. Hence CAPTCHA on the button should at least discourage software devs from automating the process of unpausing.
No, I don't think that will happen at large because there's no good reason for it.
If this is the error that you're getting, then hitting unpause won't make the certificate requests start working. You'll just go back to receiving the persistent error messages from before the pause.
What do you gain by automating it? This isn't an error that you'll experience in day-to-day successful operation. It's not an error that reoccurs after resolution because it can be removed for years with one action. This lock will only happen if a cert request is consistently broken for a really long time.
Fixing the underlying cause of the cert issuance failures requires human intervention anyway, a human can easily click the button. They also provide first-class support for bulk enablement.
The motivations for automating button are extremely small.
