Eh, I can only talk for myself. Sure, there might be people out there who liked such things because they were rare, but I like things because I like them. I've owned more guitars with basswood bodies than anything else and more guitars with rosewood fretboards than anything else and more guitars with "regular" dot inlays than anything else, and I love all of those things. Basswood bodies, rosewood fretboards, and "regular" dot inlays rule. But I've also owned a guitar with no inlays at all (on one extreme) and with an elaborate tree of life inlay (on the other extreme), both things that are pretty rare. And they both rule (plus, I've owned guitars with offset dots and non-dot inlays such as the Les Paul boxes/rectangles). I've only owned one guitar with an ebony fretboard (my new one), but I've always just loved how ebony boards look. I thought they looked awesome 20 years ago and I think they look awesome now. As a bonus, they also sound good. That's part of why I really liked the rosewood board on my RG1527. It was super dark. Almost black in color (assuming it was properly taken care of and oiled at least once every 1-3 months).
I don't go for things because they're rare, but I also don't go for them because they're common. I go for them because I like them.
