There always seems to be a trend that people of minorities seem to be the most outspoken and I think it's understandable given that you want something that you can actually use. As a designer and vendor, you're trying to accommodate the most amount of people while also keeping prices as low as possible to make it more accessable to the wide majority. That means there are certain layouts that you can't support, and as much as I'd like to accommodate minivan, I can't see the demand of the layout over the past few years really justifying having it included in an extensions kit. As a kit with 100 MOQ every key proportionally increases prices a lot, and as a vendor it's harder to buy something out when it costs more, leaving more risk for it being cancelled. I know that TKC had their recent minivan run, but numbers were never shared, so it's not like I can support something I have no clue the demand for other than a few people asking for it over the years.
