These events are emitted for every navigation request which isn't really efficient. Also upstream has removed the observers that provide these details as part of network servification https://chromium-review.googlesource.com/c/chromium/src/+/805008 and https://chromium-review.googlesource.com/c/chromium/src/+/786320. We are removing it as a part of chromium 66 upgrade.

Proposed alternative: Users can use the [webRequest](https://github.com/electron/electron/blob/master/docs/api/web-request.md) module which provides similar navigation details on a subscription basis.
