There would definitely be a lot of drawbacks.
I suggest starting with [edit] v0.7.11 and then install kernel 4.4.138-1100
(I can't suggest anything with 4.4.154 yet because there's an i2s bug I haven't tracked down yet and I don't know which one it starts in, but I'll be finding that out soon.)
I'm personally using 4.4.138-1100 with a single tweak to the rockchip VOP driver source code to enable 4K framebuffer console.
Later today I'm going to attempt to re-arrange the device tree to re-enable sdio0 (which will allow our wifi modules to work) and disable pcie.
If I get that working, I'll post the edit.
