Right, but it requires a new version of find, and thus will be non-portable. Besides, the output is not the same -- "find . -type f -print | xargs echo" will print the files with paths relative to the current directory, and "find . -type f -execdir echo {} +" will print everything with "./" (ok for "rm", not so ok for "echo"). Plus, you can't do some other nifty things that xargs can do, e.g., limit the number of files passed to the command.
