It was announced in the NEWS which is online here: http://developer.r-project.org/blosxom.cgi/R-devel/NEWS and available as an RSS feed. (If you prefer Twitter, feel free to mirror the RSS feed there, if that's possible. I don't use Twitter, so I won't do it.) It seems to have become known here essentially immediately, so I'm not sure how an announcement would help. For the reasoning: there's been a general trend to making sure packages work even when other packages don't use library() or require() to attach them. This is a logical step in that direction. If your function foo() uses the graphics plot() function but doesn't explicitly import it, then your function will fail if a user tries to run it while graphics isn't attached. I suspect dispatch may also be faster if it is imported than if R has to search through everything on the search list.
