An awful lot of production setups are capable of handling JTAG already
so don't have much of an issue here. Certainly as a developer my
preference here would be for fast JTAG over SD card - it's at least as
fast, there's only one system involved and it works just the same no
matter what the state of the system is.

Assuming the hardware can cope with it, and there's component cost,
board area and mechanical concerns to address before it gets designed
in. There are a lot of systems where it would be useful but there's
drawbacks you have to bear in mind when pushing it.
