I'm the guilty one who added the version field (though back then, it was added to a Buffer object, IIRC). I found it very helpful in debugging GC problems -- I would have a problem where memory was being stomped on, and trace it back to a prematurely freed and reused header. But in order to figure out what was going on, I needed to trace it back to the point of allocation of the header, but headers get reused so frequently that setting a conditional breakpoint on the address of the header was useless. So I added in the version number to provide something to set a breakpoint on. It is very possible that this is no longer useful; I haven't been working on stuff where I have needed it for long enough that the code has mutated significantly. Is it still useful? If not, then go ahead and rip it out.
