That's not a good reason to not change it. Keeping it in sync with the kernel
should not be the showstopper for reasonable changes.
I agree that it's sometimes useful to not needlessly change complex
frameworks like UBI or mtd(-nand) to be able to apply later bugfixes or
features from the kernel, but this doesn't match for these trivial
changes in a simple framework.
