Why not? The DS and DL are able to compress RAW files.
The DS/DL/et al are not actually doing compression, they're just
writing an array of 12bit values as 12bits-packed rather than 12bit
in 16bits cells, the simpler implementation. The reduction in total
file size demonstrates this.
That said, since these cameras can do JPEG compression, I'm sure
there's enough processing power to do lossless RAW data compression
through a variety of algorithms. It's really a matter more of
buffers, speed, etc.
