Since it seems like this not only improved sizes but also performance I can't wait for some benchmarks and comparisons. If you don't have a separate GPU for inference, every single GB matters so a comparison between specific Q4 Quants is really interesting to me.

Currently I very much can't decide between going for a bit of a lower Q4 Quant to squeeze out a bit of buffer and ctx or wondering if a slightly higher (IQ4_XS vs Q4_K_M/XL) is worth it
