Shouldn't we keep this logic as well?

Yes, probably I should not delete this logic. Based on our discussion, I thought
I should keep the old logic as is...

However, if we keep this logic, suppose we try to manually set up a new
"ChromeBox for meeting" device. During the OOBE flow, because |is_remora| is
true, EnableLoginLayouts() will not be called, which might violate the case
described above in 1). 

Actually I feel a little confused about this part of logic here. I tried to
hard-code the |enable_layouts| to |false| and tested on the device, and it seems
nothing is affected. It seems the active input methods will be enabled by
SetApplicationLocale() in the network screen anyway and it doesn't matter
whether we enable these input methods here. +alemate@ suggestions?

I don't understand this. Do you mean "by connecting USB keyboard"?
I didn't know this is possible. In this case "is_remora" must be true only if
shark-remora OOBE is in progress. If no shark device is connected, is_slave must
be false.
Did you try selecting any non-Latin languages?

&& !is_remora as well?
