Chrome Version: 63
OS: Chrome OS

What steps will reproduce the problem?
On Chromebook (say, Pixelbook), follow instructions Enable Developer mode (which *wipes data*). For example:

What is the expected result?
Each subsequent screen reminds the user that Chromebook will be wiped.

What happens instead?
Along the way, a simple screen appears that prints:

  (Orange "!")
  OS verification is Off 
  Press SPACE to re-enable.

Also, after pressing SPACE, one reaches point-of-no-return and Chromebook gets wiped.

Background: I was helping someone with Chromebook who somehow reached the screen.  Without prior context, I figured "oh, just re-enable verification, which is probably a good thing" with out realizing the graveness of the situation. I ended up wiping the device (oops).
