This detection API let the MDM applications in effect ask the operating system if it had been compromised. Jailbreak exploits typically change a number of operating system files, and exploit one or another low-level OS features to let users directly load their own or third-party applications.This isn’t exactly a permanent victory for jailbreakers, since an API is just basically to protect users from malicious ones, but it’s assumed that there could be extra exploits from the removal of the API.
