Right... Bash is a shell, but your interaction with it is controlled by a terminal program. Unless there are some real changes to cmd.exe t̶h̶e̶n̶ ̶i̶t̶'̶s̶ ̶n̶o̶t̶ ̶t̶h̶a̶t̶ ̶i̶m̶p̶r̶e̶s̶s̶i̶v̶e̶ . You can compile a native bash and other utils now yourself, it's not that hard.

EDIT: It's more like a Linuxulator from BSD, which is certainly cool.

You seem to completely miss the point of what they did. It is not a simple Bash recompilation for Windows. It is a way to run Linux (Ubuntu) binaries on Windows.
