Because they try not to be broken, and only ask for what is sensible for that
request rather than sending the same Accept headers with every request. After
all, if my client has asked for a document, sending text/html is necessary and
text/plain seems to be conventional but chemical/pdb is probably superfluous.
I mention the latter because Arena, having read my mailcap, sends that out when
it asks for html documents, etc.
