We would like to request the feature to retrieve information about all created building blocks in the workspace as part of a building block definition. A possible and probably elegant way to do that would be to extend the "context metadata" input variable types with a type for "Workspace Building Blocks". Comparable to other "context metadata" input types, this input would hold a list of building blocks that are currently booked under the workspace (probably including the one that contains the input itself in case that building block was created), and would dynamically trigger updates on the building block with this input as soon as new building blocks are created/updated/removed. The list of building block can then be iterated, filtered and processed inside the Terraform code. Having this kind of input would allow to handle relations between building blocks, that are currently very limited (one building block can only depend on one other), in the most flexible way. One building block might want to get information about other building blocks in order to implement certain permission structures or other "orthogonal" concerns.
