There are a number of active issues on the core list around this area.
This covers similar ground to core-10 - but is a distinct problem.  You
may be further entertained by the paper Martin J. O'Riordan wrote

The relationship between the name that is resolved, the fully qualified
name it resolves to, and access rights is confusing.
