I've
always heard that it was designed to make porting code from the 8080/Z80
easy.
The 8080 mnemonics were partially mechanically translatable. Easy is an
overstatement, but many of the oddballs were there to help. But the
registers had different names. So more like not too terrible...

Yes,
it's for MS-DOS, but:
1) The 8086 is somewhat, kind of, source compatible with the
8080/Z80 (if you squint hard enough)
Your not serious? Z80 or 8080 to 8086 is not too bad but the other way
is plain nuts.
