Rsync is not in coreutils and is not always installed.

If rsync is not installed, perhaps you can install it. At worst, you can build it yourself.

Yes you can use rsync, use pv with pipe, use dd or any other way to copy files. But people are used to type 'cp' when they want to copy file. And Ctrl+T to show what file is coping now and % left would be nice.

If you really need to know what a cp process is doing, you can also run strace on it.

Or, if some cp process is taking too long for a particular file, you can even set up a progress bar after the fact: search for "phantom progress bar".

Sorry, but even catching a signal and printing status the way dd does seems unwarranted: there are already so many other ways to get more/better progress displays.
