I think this is not a complaint though I sometimes wonder if something like zap split or V4V model x pay-as-you-go model will eventually come to certain relays. Say, everybody always has some sats in wallet to post and some amount of sats automatically get splitted to a relay that has LN address when a certain 'kind' threshold is exceeded against a relay. The key is relay runners can decide how to run relays of course and to not force people to pay sats to use relays, keeping it opt-in.
