I feel that comparing the registry with /etc/* is a false comparison.
Given the registry actually implies both /etc/* and /var/*, and in order
to be comparable.
I feel /etc is better than registry while /var/ may be worse
in many cases. The reason for this is the mutability scope of data stored
in these. Limiting the scope of mutability is IMO essential for POLA.
To me this means we should strive to make the granularity of 'private'
mutable storage as fine grained as possible.
