I don't like the term "upgrades" but prefer the terms "personal preferences" or "modifications". My thinking is based on a 1930 car in a 2021 driving environment. I love the look of the Model "A" but have adapted it to current conditions such as a 5.5 head, LED signals, modern water pump, Borg Warner T5 transmission, stronger radius rods, cast iron brake drums, 12 volt system, carpets, and a tachometer. Don't stress out on what others are doing or not doing... it's your "Baby"...ENJOY IT!
