I think we should alter UX for these users as less as possible. They are the
same as normal users but all their data is removed on sign out.

Not sure with this one. Was this decided?

I made the change as requested but I think skipping image selection is the
better UX:

Setting an image is a once-off necessity for regular users. Should ephemeral
users not be presented with the most common UX path, i.e. that of a returning
regular Chrome OS user?
