I dogfooded pretty much everything from the G1 to the N5, Xoom included. Until Lollipop or Marshmallow arrived, we were discouraged or forbidden from having corporate accounts on personal phones, because there weren't the necessary Blackberry-style features yet, e.g. remote wiping. I remember Honeycomb (the Xoom) having only encryption, but no wiping. At some point you could add your work account as the primary on your personal gift phones (dogfood ones were a different story), but that meant that the device got bricked when you left the company, forcing you to a factory reset — and there was still no good isolation.
I definitely had my personal account as the primary on my N5 along with a work profile and I believe that's the first device/OS combo where it was feasible, if you ignored the annoying duplicate app icons in the launcher. The first truly "tolerated" personal devices were probably the Christmas gift Chromebooks from a few years earlier, as long as you used Yubikeys.
Didn't the policies even predate Android? They definitely were there well before Lollipop. Unless they were introduced post-Aurora, in 2010 — i.e. in the N1/Eclair days, keeping the phone vintage theme.
