The reason is that I want be able to distinguish between several 
messages with the same id. Consider a message sent to a list. One copy 
is stored in your sent folder and one in another folder. You may want to 
investigate the Received headers the latter message. You would not be 
happy if, after pressing 'V', notmuch shows you the message in sent 
folder without any headers.

The same holds for pipe command. I think that the message you pipe to 
some command should be exactly the same you see in your client.

OK, maybe file name is not the proper name for it :-). In my abstract 
mail stores, I use the "file name" just as an unique identifier of the 
message.
