Is there a particular reason that no one has tried to put Transitions in any index above a 1.67?

Nikon has 1.74 transition now.
Hoya will very soon have a 1.74 Transitions lens available too.
Probably has a lot to do with demand. 1.74 is still in low use.
Here's the US website that lists Transitions in 1.74

This is a quote from the Nikon website link posted above:
Nikon lenses are also available with Transitions which provide visual comfort by automatically adjusting to changing light conditions. This helps to reduce glare and eye fatigue. Eye health is preserved by these lenses blocking 100% of UV rays. This is available in 1.50, 1.60, and 1.67 material.
Nothing about Trans 1.74.
