Obviously you need to fit the solution to the problem.  Storing meta
data in a doc is not inherently a problem.  Storing *any* data that
has high contention on a single document is a problem, but that's just
basic CouchDB in the same way that you wouldn't store the comments on
a single blog post doc.  If your meta data is highly contended then
you need to find another way round it.  But all this is a non sequitur
from the problem of getting AND semantics for keys in view lookups.
