Why chromium's crash reporter has been removed from AOSP

[DivyaBurgose]

I am trying to port chromium's crash reporter onto Android. Observed Android -N codebase has chromium's crash reporter code(https://android.googlesource.com/platform/system/core/+/refs/heads/nougat-dev/crash_reporter/), but I have seen that it has been removed from Oreo onwards.
Can anyone tell what could be the reason to remove crash reporter from AOSP Oreo source onwards?
