A combination of multiple service pages to complete one data

Hi all,

I saw a mention for user to select any number of applications to complete one Web Intents task in latest Web Intents draft.

In some cases, the user will expect to edit one image by using multiple photo editing service pages one by one. For example, some service pages to adjust the brightness and contrast, some to add animation, and some to add 3D effect. The user invokes the edit action and selects 3 service pages together. The data will be returned to intent client after having been edited.

Another example is to edit an audio by using multiple service pages to complete one music, such as drum apps, multiple track recording apps, and music creating apps.

In such scenarios, it is easier for user to invoke one intent action but to combine multiple services to complete one data as an output to Web intent client.

Does this make sense or have been discussed before?
