One easy way to avoid this error is to place the FILESEXTRAPATHS variable inside a custom bbclass them inherit it from the recipe, at least it is less prone to typos. We do not want to force users to place patches inside a particular folder (policy), instead the system offer a mechanism to place these any place you want (other recipes choose PN, for example)

Right, I think there is no tool to create bbappends from the command line.

Anyway, feel free to file a bug (bugzilla.yoctoproject.org) with your enhancement.
