nit: can this be assertNotReached or something else to attempt to show/enforce
that this class is abstract

[Moe, 2016/03/09 19:30:08]

Done.

[Moe, 2016/03/09 15:29:03]

I noticed in the existing examples under settings/ the interface is not being
returned as a property here on the output object. This makes for example
"signin.ProfileBrowserProxy" a bad type according to closure compiler.

[Dan Beam, 2016/03/09 18:21:37]

yeah, this is because of 2 things:
1) technically the type isn't exported unless it's returned
2) our compiler pass[1] handles this fancy export mechanism fragily

[Dan Beam, 2016/03/09 18:21:37]

this should not be @private if it's externally used

Done.

[Dan Beam, 2016/03/09 18:21:37]

i think it's probably better to set/inject this or just call getInstance()
directly from your classes

maybe just drop this behavior?

[Moe, 2016/03/09 19:30:08]

Done.
