@MichelleArk or @peterallenwebb , I was wondering if I could get some thoughts and feedback here? :)
Thank you!

Hello, @graciegoheen, @peterallenwebb, @MichelleArk and team, sorry to ping you again, but could be possible to get feedback on this topic?

I strongly believe this quick and small PR could enhance DBT and open the adoption of it. It would allow us (the developers) to enrich our current code solving for example (i.e. remote credentials fetching, or even remote model configs fetching).

Happy to jump into a call if needed.

Thank you!
