Err... not easily.

The filesystem layer has certain optimizations for efficiently finding
paths with svn:mergeinfo set on them (e.g., minfo-count in fsfs), so if
we introduce a new property then we won't be able to efficiently find it
in old servers.

Unless we encode its location into the existing svn:mergeinfo properties
in a format that 1.6.17 would consider valid but wouldn't affect its
mergeinfo calculations.... but that's impractical.
