I think we prefer this alternative, thanks.  However, to accept such
changes into Emacs, you will need to do legal paperwork, as I don't
see your assignment for Emacs on file at this time.

There's no need to obsolete a mode, as it isn't doing anything wrong.
It just has only a small number of features.

Then I guess we will have to make a better marketing effort this
time.  For example, we could make bat-generic-mode be the default mode
for Windows batch files, which will make users acutely aware of it.
