Sounds like the "nerd gear" option that my brother in law and I talked about. As in - why wouldn't the manufacturers offer a taller that stock top gear for the hard-core FE nuts?

Yes it would force you to shift more (in and out of top gear) depending on terrain, speed, cargo/passenger load.

But if you're willing to tick the nerd gear box on the option sheet, I'd bet you'd also be willing to shift more for the FE advantage if it's right for your situation.
