i get that, but i feel like nostr is one of the last options you would consider to host your paywalled content considering how the portability of data seems to be designed at its core. and eventually the goal is to have more small relays and less big ones in favor of the outbox model, so in this sense i think the decision of taking "-" into account will be for users to make, not big brother relays. so yeah i don't know if most people will respect "-", it seems like its never been easier to relay signed data though.
