The old 3 series moOde used experimental kernel and I2S drivers that the maintainer abandoned and so they eventually became unsupportable and were dropped and replaced by stock Linux kernel for Raspberry Pi beginning with moOde 4 series. Certain I2S drivers in the stock kernel already support up to 384K PCM rate for example the drivers for Allo Boss and Katana DAC's The Katana also supports DoP. These DAC's play DSD64 and DSD128 perfectly.
For other I2S drivers its up to the DAC manufacturer or driver maintainer to release a driver that supports > 192K PCM rate and then get the driver accepted into the Linux kernel.
