@bucephylus and @Fuzzbass,
Admittedly, I skimmed a bit, but here's my additional thoughts...
Scientific data on tonal effects due to normal wear and tear over time; actually, there is scientific data on this, including the effects on wood. Yamaha had some nice info on this, implemented a "feature" (process) based on it, but IMHO way overpriced, so it didn't go anywhere. Lots of other scientific stuff on pickup changes over time, how to stress new pickups or wind new to mimic that etc., by many vendors.
I'm also not a fan of refinishing old instruments, and would always wait until it's unavoidably necessary even to re-fret. I personally believe preserving as much of the original as absolutely possible is important... not only for valuation, but also the playing experience and tone.
IMHO
