Ability to Group Subscription Keys
Currently the subscription keys are issued at the 'Product' level. These products basically map to resource features. It is great that subscription is managed at this granularity but it would be better if the subscriptions can also be managed at higher levels. I may want to use the same subscription key to Axcess multiple products (or bundles) or even go to a higher level of managing APIs at multiple bundles level (or container) with a single key. This way the developers can use the same subscription key across products, bundles or container levels as configured by the publisher of the products if the publisher wishes to manage the subscriptions in that manner. Right now the subscription is only limited to product (resource) level making it difficult to migrate existing subscription models from other systems to APIM unless their existing subscription models are changed.
