I would rather not have a separate public variable here; you can always get the default with SKIP_CREDENTIAL_SUBSCOPING_INDIRECTION.defaultValue

This looks really close to me; if you can add some details on how you tested this I think we can merge it almost as-is. Thanks for working on this!

Can we move this into the description? The description should ideally be detailed enough to understand the config without an additional comment explaining it.

Thanks for your input on this @eric-maynard !
Do you have any suggestion for a unit test? I didn't find a way to check the properties of the loaded FileIO to see if it contains credentials or not.
For now I've only tested that it's working on my setup.

I see, but how did you test it's working? i.e. how did you confirm that the credentials vended were not subscoped?

I did some manual tests and verified it's working (it was not working in my setup when Polaris was subscoping the credentials because I cannot reach aws endpoints directly).
I also observed the traces and there are no calls to aws.AssumeRole anymore
