When performing a "emerge rsync", I feel that the output is far too verbose to be of any use. Page after page of text flies by, and is only really of any use if there's a problem. Why not have a verbosity flag that can be set at the command line, or maybe in a config file. A nice discrete summary of what's going on should suffice for most users.
It doesn't hurt anything and as noted in the rsync man page: gives you something to look at.
