We've been talking about a general mechanism for inherited properties
for a *long* time. If implemented, such a mechanism could be used for
repos-dictated config through inherited, versioned properties.
Another possible use could be log message templates.
As I recall, there were a few reasons why inherited properties haven't
been implemented. One is the client-side storage and lookup, which
wc-ng has helped with. The other is what to do with non-checked out
parent directories, which you mention above. Another problem is the
various authz issues, similar to the infamous issue 3242 problems we
had with copy and move. And lastly, we haven't yet hammered out the
issues surrounding what to do with potentially conflicting properties
within the tree--though that might have been specific to log message
templates, now that I think about it.
In any case, there could be many uses for inherited properties, but
not all the kinks have been worked out. Though it might be time to
