I can see your point, but for compatibility reasons all browsers
generally cache intermediate certificates and will automatically use
them should a site fail to provide them, and in addition they will
skip any extra certificates a site may send. If gnutls doesn't either
do this automatically, or at least provide a means for applications to
do so then it is going to lead to a bunch of frustrated and confused
users.

Having spent quite a lot of time explaining how to address missing
intermediate certificates even to the administrators of banking web
sites, I think it will be a lot easier all round to accept a little
more complexity in this part of the code.
