Why isn't triple scroll a thing?

If twin scroll works better for 4 bangers and 6s, would a theoretical triple scroll 6-3-1 manifold pairing 1to6, 2to5 3to4, triple scroll turbo have any benefits? lol I know triple scroll doesn't exist but perhaps it would be beneficial.

I think mostly because the cylinder count of most turbo cars isn't divisible by 3.
ie. it would work for 3/6/12cyl engines, vs 4/6/8/10/12 for the twin scroll.

Sounds cool, but it sounds very niche market. I imagine there are other reasons as well

Diminishing returns and complexity of the turbine housing casting.

No demand, no need. There are quad variants out there but the cost for the smaller hp gain is not worth it from a retail stand point.
