I regularly use cat in an interactive way. Most Unix users do.

cat >somefile.txt
sometext
^D

It's a very fast way of moving stuff from the clipboard to a file
without having to fire up an editor.

I'm not sure a prompt would benefit very much here, since this is such a
common operation once you learn it.

In MS-DOS to create a file you do "copy con: file" and then you also get
a blinking cursor with no prompt. Yet this was just something we did
with MS-DOS.  Not sure a prompt would have gained much.
