Instead, we only develop a build script and Kconfig. It's a sort of "stub" (for lack of a better term). If that item is configured, our build script will download the sources from the 3rd party (I think the URL is configured in Kconfig, so developers can locally host all their dependencies) and then compile it with the rest of their build. See, for example, in the nuttx-apps repo: math/libtommath. In the case of YAFFS, if someone wants to implement such a stub, it should depend on ALLOW_GPL_COMPONENTS, so that the developer who chooses to use it will first have to explicitly accept that license.
