Isn't there some deferred or other state that better expresses the

This is another reason why OpenWRT IMHO should become a Yocto layer (or 
set of layers preferably). It would relief the OpenWRT community from 
maintaining a lot of generic infrastructure and open source packages. 
Freeing up their resources to work on what distinguishes OpenWRT from a 
generic Linux distribution.

Things like dm-verity and SELinux for smaller and targeted embedded 
devices could than be picked up by the much larger Yocto community and 
become available for OpenWRT almost for free or there would be at least 
the benefit of the main infrastructure being there.

FYI: there is already such a layer 
(, but still very limited.
