I note that Electrum v3.0.6 has an option to use multiple change addresses. It is off \
by default.

Without commenting on the merits of this proposal, I?d just like to correct this \
common misperception. There is no necessary additional cost to the network from the \
count of unspent outputs. This perception arises from an implementation detail of \
particular node software. There is no requirement for redundant indexing of unspent \
outputs.
