| Jools, there will always a segment that wants things exactly as they left the factory. I'm happy to say that I've never been in that camp.
Very few things in this world have been made with a "money no object" approach (Prince Jeffries' with the whale foreskin-covered bar stools spring to mind). In those cases, items have been selected because they were the best available at the time. If technological progress has improved things then I see no problem with upgrading.
Everything else has been made with price in mind.
Keeping the originals for a possible sale in the future is prudent because, as something becomes a classic, the buying market (not the dreaming market) will place emphasis on originality.
These comments are only for performance parts. Anything aesthetic is purely down to personal taste.
