Over the last few months, I had sent emails with follow-up suggestions, questions and (minimal) patches to R Core (two) and R-Devel (one). Not one of these emails was met with any follow-up I am aware of. I will resend them here so that they will at least get archived in case someone else ponders similar questions at a different point in time.
