In my brain I'm incline to fuse following:
a) test system
b) build system
c) source control/git/..

This kind of makes sense since each of these is dependent on same file
layout, naming conventions, scripts, etc.

I agree with your statement above and with Peters on the opinion on the
same subject. That is, writing code to create previous versions would
really be an orthogonal issue to testing ability to read previous
archive versions. This latter would/should/could be implemented by
making the the "test infrastructure" that much more elaborate. It
doesn't take too much imagination to figure out how much enthusiasm I or
anyone else could muster up for that.

Right. I'm not even sure it could be done for binary archives given the
evolution in compilers/libraries etc.

since binary archives are not likely to be used for longer term storage,
the problem would/could be ignored for this case. Of course someone
would raise the issue about using serialization to pass data on the wire
between different versions of the application.

This is all quite interesting. But I'm inclined to just accept the fact
that I/we can't solve every problem. The number of cases that this
problem has actually occurred is pretty small, especially when

Since I burned myself on this in a bad way in may 2010, the number of
cases that this problem has actually occurred is very, very small.
Somehow I'm thinking that it won't happen to Mr. King again at least.
