Is your feature request related to a problem? Please describe.

This task is part of the effort to rework the Starter Page Template Picker for new pages. This part of the initiative will focus on modifying the API call /wpcom/v2/sites/{site}/block-layouts to include the supported_blocks
query parameter which will be used to only include layouts that have met a server defined threshold of supported blocks.

Goals

• This issue is to simply serve as a reminder to wrap up and discuss any lingering design review elements that come up in the course of developing the Modal Layout Picker.
