I've never actually made a palette, but it just doesn't seem practical to me to expect theme creators to always find a contrast-safe 16 colour palettes. I would imagine that it even seriously restricts the range of themes that can be made. I can imagine that such a thing is possible for smaller palettes like say 3 colours though, but then that's not actually useful for UIs.
I think the fact is that small palettes come from the days of lower resources, not from efficient program design.
