I think there are sort of two perspectives to this. The perspective of David Gilmour, and the perspective of people that arent David Gilmour.

I've not read the book mentioned but id imagine the modification and changes of his guitar have been either out of necessity or out of interest, but at any rate, hes, at whatever point, arrived at the instrument that makes sense for him. To everyone else, its david gilmours guitar, which carries a heavy enough connotation in its own right, regardless of who made the parts that its made out of.

I think it's interesting that so many iconic guitars have been modified in some way, especially fenders where necks have been swapped about. Wasn't claptons famous strats both partscasters & Niles Rodgers strat has a 50s body & a 60s neck.

Even Peter Green fubard the pickups so they were out of phase on his lester

What I think it shows is that guitars are made for playing & messing about with, especially fenders, which from design were made to easily swap parts. Not to be kept with tags on in their case under the bed.
