@Stephan202 Internally we are blocked on SB 3 upgrade, do we want to add pause renovate here for the time being?

@rickie good question. Generally that might be a good strategy indeed. On the other hand, I expect that we'll not suddenly start writing rules against SLF4J internals, while the public API remained mostly stable. Since we don't pull the dependency in at runtime (it's declared provided), I think we can actually just proceed :)
