I'm running CURRENT on my laptop, so I use drm-*-kmod, and most of the time packages work for me. When they don't work, yep, I need to rebuild them with up-do-date /usr/src, but this is process of tracking CURRENT! I believe same can happen with a STABLE, if somebody is not very careful with merging their changes. In that case you would also need to rebuild, but you would also need to _update_ first. How do you update bare /usr/src? I can't understand why would you need to rebuild anything if you are running RELEASE and packages? If that ever happened, this is definitely fault of either someone's merge to stable, or maintainers of drm-kmod. But this can't be taken as a good reason to have those stub sources.

The problem in my view is that we ship something that is useless in vast majority of the cases. In majority of the cases work starts with: rm -rf src && git checkout ... For those, who not yet learned that this is the normal beginning of work, the mere existense of the directory is misleading. -- Gleb Smirnoff
