That change has taken only 2 kinds of reset into account - warm reset and S5 reset. There are other kinds of resets during the boot flow. One such reset scenario happens when a user switches from developer mode to normal/secure mode in ChromeOS. That change unfortunately has caused regression in those kind of resets.
