"tee" element makes the allocation query fail, so that will never be
used (we always double check the caps features against the allocation
for backward compatibility). If tee finally had code to intersect the
allocation query, the upload meta would only be negotiated if all the
branches supports it (it's an intersection). If you add a branch
without the negotiated feature at run-time (and this was supported at
all) it would fail with not-negotiated. We could think of a
renegotiation path eventually though (leave the new requested pad idle
until upstream dare to renegotiated).
