Honestly I do not know about pitfalls but using I have used zImage will doing board bring ups of new SOCs. It is easy to load a zImage from a IDE like CCS in TI's case. 

When we get the first EVMs even the bootloaders are not up and running so zImage along with CCS comes in very handy. You can directly load into DDR and boot up the kernel.
