Well, Dirk has said to have given his last reply on this thread.
I (as a member of R-core) am glad about people like Dirk who
take some of our load and helpfully answer such
questions/reports on R-devel.

To the issue:  I also don't see what your point is.
R works with these so libraries  as intended  in all cases as
far as we know, and so I don't understand why anything needs to
be changed.
All these libraries "belong to R" and are tied to a specific
version of R  and are not be used outside of R,  so I also don't see
your point.
