Just got back from vacation so sorry about the delayed response. There are a few possibilities as to why zero offset is popular aside from the people that want the wider stance.
1. Most aftermarket UCA's require approximately a +00 as do aftermarket long travel kits
2. Companies like KMC, Volk and Titan that build mass qty forged wheels want to get the most out of their forgings so they build in a way where they can be drilled 6-135 for Ford or 6x139.7 for Chevy/Toyota without having to have separate tooling just for Ford. Since Toyota requires lower offsets to clear factory UCA's these companies build them with Toyota in mind due to higher volume aftermarket and the Fords just get what works on Toyota. If they built a more positive offset for Ford they'd need a separate forging for Toyota. Take the Titan wheel for example. In my opinion that wheel was designed and engineered for Tacoma/4Runner based on the load rating. It just happened to clear the Raptor brakes so they started drilling 6-135 and marketing towards Raptor owners.
When you look at Innov8, they'll build -6, +6 and +25 since each set is tailored your needs. Not mass produced. But they're also a little heavier because design them with maximum durability in mind.
This is all speculation though so don't quote me.
Once my new set arrives and is test fitted I'll be adding one more design and doing custom orders. Very low volume though. It's more of a side gig for a major supplier we deal with.

deeper bead grooves for bead security
custom finishes since they'll be made to order
