Based on discussion that happened on the PR that introduced the size-tracking tool, we want to have another threshold for the raw byte difference. This allows us to better control for which changes the size-tracking tool should report a difference. See: https://github.com/angular/angular/pull/30070#discussion_r278332315 PR Close #30257
