Not sure what I'm doing wrong for the content checks test to fail still.

Thanks for this submission! I will bring it up in triage to see if we will consider it for review. We may want to include these as built-ins given their mirrored file versions, or we may ask for these to be built as provider functions. Thanks again!

Any estimate for when this feature will be released?

[crw]

Apologies, I failed to report back on this one. This was happening around the time that provider-defined functions was being released, and there was some discussion as to whether these are more appropriate for a provider function. The process for determining whether something should be a built-in function or not was less mature at that time. Even if this was found to be acceptable, we would ask for this to be implemented in the local provider. In fact, you can see that the direxists function was implemented: https://registry.terraform.io/providers/hashicorp/local/latest/docs/functions/direxists

I think the path forward here would be to implement dirset (aka directoryset) in the local provider. Please comment if you believe another solution is more appropriate. Thanks!
