Most if not all packages will need a re-installation, not only those you
talked about (in particular there is a new snow on CRAN already). Hence
I think it is not worth the effort to find out what "old" means. Please
note this may change during the development cycle and you may even need
one or more re-installations before the next R is released. S4 packages
may even need re-installation if other S4 packages (the former depend
on) change.
Best,

It would be convenient if, under R-devel r56422, packages that require
re-installation because they do not have a NAMESPACE were marked as
old.packages, so their lack of functionality can be discovered more easily.
