@pmartindev have you tested this change?

[pmartindev]

@stevehipwell no I haven't yet. This one will be somewhat challenging to manually test 😅 I thought we would have a discussion on if this is meets the criteria for solving the initial issue. Do we want to change how rate limits are output, or do we want to continue to only output this as debug output? I think there's an argument for both, and the solution may just be to "switch to debug mode" to validate rate limits.

I'm also not sure if there is a broader discussion on if we should update from the legacy logging system https://developer.hashicorp.com/terraform/plugin/log/writing#legacy-logging

[stevehipwell]

@pmartindev I suspect that you wont see the logs even after your change as the default provider log configuration is none and I think this applies to the legacy pattern.
