An Alias List (All Constituents) endpoint would be great.

Alias support is coming soon! We will be starting the first batch of stories to introduce this feature set this week. Keep an eye on the changelog to see when this functionality is introduced. 

One point on this is that it would be great to return which Alias the value was associated with. Right now if you search by alias, you see the results, but don't know if it was in the right type.

Also would like to filter to constituents with that alias at all. We use Alias for lookups from other systems Unique Id.

Sorry for saying alias so much.
