to elaborate on this a bit more
my phone OS has no big single account with a profile picture at the top of the settings list
it has an Accounts section, where each app can do its own thing, and google is just one if the items in the list (email hidden for privacy)
that's how it should be

in short, i don't believe that your OS needs an identity layer in the first place
leave that job to the apps running on top of the OS, don't lock users' choice into a single set of valid options
