FWIW, when I was working on deprecating the old pc machine types, I 
originally wanted to stop with pc-1.3 (since I was most bugged by the 
different naming between "pc" and "pc-i44fx" in the help output). I then 
only put the 1.4 to 1.7 machine types on the deprecation list without 
anything in mind. Now this became useful for the 128k bios rework... so 
maybe we should continue deprecating older machine types for other future 
reworks that we don't envision yet.
