Heck, if I were a purist, I'd have to stop restuffing caps.
Any purist is one only up to a point. Any restoration is a compromise.
If you think of it, most famous artworks are now full of today's repro paints from all restorations. Da Vinci, Rafael, all those Sixtine Chapel pics....so, what, do we stop considering Mona Lisa as a Da Vinci's work then? or does it ruin its value?

Fundamentlism is always....bad. At best it is impractical.
