I think that it should be possible, but not obligatory to say this.

I think I agree with Luc's comment that it should be possible to say  
this, or say the more simplistic version that ignores the details of  
HTTP clients, web servers, etc.

In some cases it might matter which client was used, e.g. if it had a  
bug.  So in that case, the provenance would be "incomplete".  However,  
this is a slippery slope: one could keep adding detail beyond the  
point of reason, and there might be privacy concerns to making the  
provenance too detailed.  I think it ought to be up to the provider  
how much detail to give.
