Because resize-mini-windows may be nil. And the message may be invisible.

Another question:
When emacs displays combination of the prompt and the message, if user input something, doesn’t the message disappears?

The current code doesn’t display the message transiently. It displays it forever. User needs to press a key to restore to the prompt. Is this a bug?

Do you mean the scene “Foo…” followed by “Foo…done”?
I don’t think this is a problem. These are just status which are not important. And they disappears quickly when user is busy editing. And the really important ones may put an indicator on the mode-line.
