Can there be any larger hindrance than having to rewrite/redesign? Most of the stuff (by lines of code or time spent writing the code) doesn't have enough data items to even theoretically be data-parallel. High percentage of code also doesn't live more than few days or weeks, so spending even little more time to write it than is necessary is generally a bad idea (this is likely a somewhat unusual aspect of game development though).
