It is not that I am not taking your word.  There are some unique (to me)
approaches in R and some of them are subtle.  I am also taking criticism from
the other side, because, as I said, some conventions collide.  When Martin said,

I understood that "tied to a specific version of R" meant that (Debian/FreeBSD)
R packages should be updated in lock step with R.  So, on Debian, changes in the
r-core package never necessitate a bump of r-cran-*?  In other words, the
libR.so interface is guaranteed to be stable across releases?

Understood.

Pedantic is fine.  I give credit!  I would not be investing my (comparatively
minuscule) time if I did not appreciate R.  I would also not be doing anyone a
service if I released a flawed FreeBSD package that did not do the project
justice.
