Performance control of embedded content #911
Conversation
| When it comes to optimizing performance, websites and apps are limited by the performance of the external content they embed, these can be 3rd party sites, 3rd party apps, and even content from other organizations within a company. As a result, being able to control the performance of embedded content is crucial to improving the overall performance of a site or app. | ||
| This proposal has two primary goals: | ||
| 1. Improve users’ satisfaction with their OS, browser, and applications via formalizing methods of constraining the resources available to web content. | ||
| 2. Provide information to help developers improve the performance of web sites and apps through reporting when performance is negatively impacting end-users and/or applications hosting the site in a frame. |

I might swap the order of these two points, since the second goal is required to be achieved for the first goal to be achieved.

I have it in that order to lead with and highlight the main driving factor, which is to improve end user experience. And you are right that the second goal is necessary to achieve the first. But I wanted to put emphasis on the end user impact.

I'm not sure additional standards work is a good reason to go with one approach and not another, so I'm not sure if that is worth listing

The reasoning here was that even if we wanted to go with the custom mechanism option, we'd need to re-do a lot of the work that Document Policy already does. In particular, it seems like HTML spec changes are more challenging to get through, so defining our own would add that while not providing anything fundamentally better compared to Document Policy. I can remove this item.
