First, runemacs.exe is by default _not_ compiled with
CHOOSE_NEWEST_EXE defined.  I don't think we should turn that feature
on by default, because the result might be unpredictable: no one can
guarantee that the newest emacs*.exe is what the user wants.  E.g.,
what if some older version is rebuilt and re-installed, or if the user
downloads and installs an executable from another source whose
timestamp is older?  This kind of stuff is not for the faint at heart,
IMO, and that's why it's turned off.

Not if you invoke it from a cmd.exe window.  And that is an important,
albeit relatively rarely used feature, because it allows several
important use cases, such as:

  . using Emacs in -batch mode
  . starting Emacs from emacsclient
  . starting "emacs -Q" to test if some problem happens then
  . if Emacs crashes, the backtrace is printed on the console as well,
    which is more visible than when you invoke via runemacs

There are use cases beyond those covered by what you describe.  E.g.,
emacsclientw is inappropriate when Emacs is to be called from a
program that must wait for Emacs to finish editing, like when it is
used as EDITOR from the various VCS programs.
