Why not have all retouch stages (including raw scans). Here are a few reasons for it:
1) There's a 50% retouched box and I wanna make a 100% retouch, It would be much more precise to restore a raw scan than an already retouched one (which already contains slight sort of "modifications")
2) All people are perfectionists and they might consider a 100% retouch not as exact as just a cleaned original box.
3) Some people might think that an existing retouch is not good enough for them so they would like to do one themselves
4) Having all stages of retouches gives a great opportunity for "beginners in restoring" (like me

) to be able to compare different stages of a box in order to understand how good their retouch should be
P.S. Please, review the NES contributions, they're getting stale!! TY
