All it takes is somebody to rewrite cd9660 to be a r/w filesystem :-)
It's not trivial though, because iso 9660 is essentially a sequential
archive with a index up front, so if you change the size of one file
all the ones after it move as well. I guess as long as you don't
want to make any files longer it would be relatively possible.

Never attribute to malice what can adequately be explained by incompetence.
