Because subscribers are not read-only. They have the ability to be promoted
to origin status. If you don't ever intend to promote a node, you can set
forward=3Dfalse for it's subscription and achieve some savings on the node =
(by
not storing log info).

If you want subscribers that really don't cost any extra to the cluster,
have you considered sl log shipping?
