Thanks for the feedback! I actually just now finished writing a larger proposal on “f-dicts” (f{}), including a discussion on a potential conceptual relationship between the f in f"" and the f in f{}. Some people may feel the connection is not strong enough, but I feel that there is definitely some connection. I don’t want to spam by pasting excerpts of my post here, but if you are still interested, please see my thread and expand the section “Is there any connection between the f in f{} and the f in f-strings?”.
