(info "(eshell) Top") says

    [Eshell] is intended to be an alternative to the IELM REPL for Emacs
    and with an interface similar to command shells ...

The functionality of setting a working buffer would be for when Eshell
is being used as an alternative to IELM, and it would have the same
semantics as the equivalent functionality in IELM.

I agree that when Eshell is being used as a command shell the only
significant thing would be default-directory.
