Get-AzureSubscription vs. Select-AzureSubscription -PassThru

[pcgeek86]

• The Get-AzureSubscription command returns objects of type: Microsoft.WindowsAzure.Commands.Profile.Models.PSAzureSubscription.
• The Select-AzureSubscription -PassThru command returns objects of type: Microsoft.Azure.Common.Authentication.Models.AzureSubscription.
• The AzureSubscription object model lacks some of the properties that the PSAzureSubscription object has.
• The property names for AzureSubscription and PSAzureSubscription objects are inconsistent with each other.
  • One has a Name property, while the other has a SubscriptionName property.
  • One has an Account property, while the other has an Accounts property.
• Both the AzureSubscription and PSAzureSubscription objects represent the same entity (an Azure subscription).

Question: Why are there two different object models that represent the same entity?

Action Item: Please change the Select-AzureSubscription command such that it emits the same object type as the Get-AzureSubscription command.

I can kind of see what is happening here:
Get-AzureSubscription returns ALL your subscriptions (one for each member of the Accounts Property). Selecting just one, produces just that account, which has an account (that is just a string). The Accounts property of the PsAzureSubscription is an array of AzureSubscription objects. So what is happening sort of makes sense.

Having said that, not sure what SHOULD happen. I would have expected both methods to have provided the same result. I can duplicate the issue here.
