I believe that this was done deliberately.

FWIW, you can do `C-x C-f C-n' to get what you want (at the cost of another
keystroke). The `C-n' retrieves the default value, which is the name of the
current file.

If you often revert a buffer (e.g. re-read a file), you might consider
binding `revert-buffer' to a quick key sequence - I use `S-f1', for
instance.
