Not actually related to this change, but can you order the properties in Required -> Optional -> Computed order? I'm a big fan of that to make it easy to immediately see which fields are settable.

This can probably be removed

Oops, sorry, this is a remnant of my futzing around with customize diff -_-

If you want to keep the checks I won't tell you no, but they aren't necessary if you check by importing

I think in this case import wouldn't actually check them, because they're computed fields not set in the config, so I believe without the checks, if the fields just aren't being set, ImportStateVerify won't complain. Because (from what I understand) ImportStateVerify just creates a new, empty state, imports the resource again, and checks it against the state from creating the resource. If there was a bug where these weren't being set, in both cases it would have them not set, so ImportStateVerify would think that's fine. And because they're computed and not config fields, there'd be no diff.

Cool, makes sense! Regardless, you can still take out testAccCheckGoogleProjectExists

nit: can you align the =s here? (as if you were to run terraform fmt)

this is pretty much identical to testAccProject_create (which lives in resource_google_project_iam_policy_test.go) if you wanted to reuse that (a few other resources are doing so)

I have a weakly-held opinion that it's better to have the configs for semantically different things separated, even if the implementation ends up looking the same, to minimize unintended consequences of changes. But if you feel strongly about it, I'm happy to change this.

No longer ForceNew on every little change to an App Engine application. Now adding an App Engine application to a project doesn't force a new project, only removing an application from a project forces a new project. Also, updating the location_id forces a new project, but all other fields can be updated in place.
This depends on #1620 and should only be merged after that is.
