Hmm, I'm a little concerned about this interface being unwieldy, but I'm not sure whether the thing I want is possible or not...
My use case for this is shown in this example policies config. Basically I have a bunch of policy set resources, and each one needs to provide a bunch of workspace IDs, which I'd rather access by name. But with per-workspace data sources, I'd need to write four extra lines of configuration for every name I want to use, and I'd still have the problem of double-bookkeeping, where I have to keep my set of tfe_workspace data sources up to date. That's not too onerous in that toy example, but in a real-life situation with 50+ workspaces instead of just 5, it's kind of brutal.
Would it be possible to also make a tfe_workspaces or tfe_workspace_ids data source, which would have an ids attribute with a map value? Or is that not feasible because of something about the way providers work?

I think a data source can have an ids attribute which contains a map of workspace names and their external IDs. But in that case I think the question is what kind of filter you want to use to select which IDs should be added to the map?
If that filter requires you to specify all names of the workspaces you want to select, you end up with having to declare the the same list twice. Once in the tfe_workspace_ids data source and once in the tfe_policy_set resource. Yet I agree that this would still be better then the current solution for your use case.
But after looking at your example, I think there is a much better way to make this resource user friendly. I don't think we should mix and match workspace IDs in TFE resources. So instead of using the external IDs, we should probably just use the workspace names here.
Exporting the external ID of a workspace is only done for specific use cases (see #19 for more details), so that ID should itself not be used in other resources. I guess this one slipped through when reviewing the PR.
So I'll work on a PR to update the tfe_policy_set resource today so you can have a look at it when you get online. I think that would be a much better solution that using a data source with a map.

Please checkout PR #44 and then mainly the updated docs as those will show the UX changes when using the resource.

I just added a new data source to this PR, called tfe_workspace_ids which I think solves your use case.

given this is a Data Source this'll need to be a List rather than a Set (I'd question if this information is likely to be used in a data source, however?)

Will update it to a list 👍
Not sure if people need it, but since the info is available I think we should just return it. Pretty sure that if I remove it that within a few days or weeks someone comes to ask for it 😉
