Psychological benefit vs. effective benefit involves the danger of
destroying trust in the Bitcoin network when there are hard facts for
non-robustness while the node number looks big. Therefore, it may make
sense to establish better metrics.

In my opinion, the characteristic of being able to make use of
non-dedicated nodes should be regarded as an advantage of the Bitcoin
protocol, and not something to get rid of. Nodes being able to
contribute this way may lead to even more robustness than
decentralization alone, as they can do so without exposing a fixed
address which could be attacked.
