The whole wide arch thing is about the look, I don't think its people wanting it to be a 22B.. 99% of Jap performance cars ended up getting either wide arch kits or over fenders, and never actually had an original wide arch model exist
I would like the wide arch purely for the looks, and the wheel options.
I've seen the old school skylines with arch extensions sell for crazy money so it's hard to say how it will effect the future value of the car, Liberty Walk do over fenders on new Aventadors, mclarens, ferraris.. it's really down to the owners desire..
I would have no problem buying a well done wide arch Type R, I just can't bring myself to cut my own up lol
