Yeah, but these are just words, nothing people could use. Unfortunately the author of this document died a few years ago. Either the whole idea of userspace firmware-loading should be considered as a problem impossible to do right because of its unsolvable side effects. Or at least releasing loaded firmware should be the exception for drivers which can be sure, that the firmware is not needed in situations we try to work around here.
