There would be a significant benefit to Apple (and us of course) to be able to market Fusion drive as standard feature of OS X (maybe the next version.) But there might be some problems ensuring compatibility and smooth operation with different SSD's or something.
If it was built into OS X, I would probably remove the optical in my MBP and install an SSD there.

Well, that's what I'm saying. Someone will probably release an application that tricks the computer into thinking it has a Fusion drive installed - like TRIM support in SSDs and some of the old tricks like that.
I'm using the ATI 5xxx drivers from a particular year of iMacs to drive the GPU in my Mac Pro, for example. It's all there, just had to make the OS see it as a compatible part.
