Note that 2) is a common desire, but think about how easy it is in 
practice. When presented with two headers with conflicting header info, 
which does one use, the first,  or some combination when adding two 
fits files? This is always much harder to do well in practice. Given 
the complex arrangements FITS files can have, I have my doubts about 
this being a really useful reason outside of doing very simple things 
(in essence, saying that one doesn't care that much about what is in 
the headers or how different entities are related in fits files)
