I feel like that would come with the territory of a niche, small-batch device. They wouldn't be large enough to benefit from economies of scale, and they're not bringing in enough money to employ teams of engineers to optimize and refresh the hardware regularly.
That's the issue with any device like this with small production runs - you can't get the same bulk discounts on components for a few hundred devices as you can when making, say, 10,000. Unfortunately, larger runs require larger investments, and most people who are interested in these projects do not have the resources to back such a big project.
