Incidentally the words 'This should be done with the current version of R-devel (or if that is not possible, current R-patched or the current release of R' translate in plainspeak 'run R CMD check --as-cran with whatever version of R provided it's not outdated'.

That's as interesting as the English language makes it -- please note of the expression 'should' as opposed to 'must', and the list of three options of R versions.

I maintain two packages on CRAN, if that's what you're asking.

Does it?

I presume that the issue is this: some packages are written solely in R, hence, unless one uses a particular and outdated syntax, there are no differences between R-devel and and R-current, whereas packages that call C/C++/Fortran code are subject to the vagaries of compilers and operating systems, and using R-devel should help future proofing the package, while maintaing compatibility with R-current.
