It is usually used for writing firmware.
The firmware contains several blocks of continuous registers.

I think it is worth, even this only saves several numbers of control transfer.
This patch could replace 3 control transfers with 1 control transfer.
If you could do it with one step, why do you use 3 steps?
Besides, a control transfer is a complex process.
I think this could reduce the loading of both software and hardware.
