As far as I know, early DOS days it did keep EXE and COM separate.
Then some system programs changed, but to avoid confusion they
kept the old extension.  The system can tell them apart.

CMD came from OS/2, and BAT from MS-DOS. Windows accepts both.

It does seem that it could separate EXE/COM from BAT/CMD, but as
I understand, it doesn't. 

I remember EXE back to TOPS-10 days, but that was before I knew
about RT-11.  Somewhere in the DEC days, anyway.
