I used this in citus to make the logical replication sender of the shard rebalancer use a higher CPU priority[1]. I had no clue, until now, that that logic got completely broken in PG15 (which we coincidentally added support for in the same release). I'm not entirely sure if it's worth a backpatch. This citus feature probably isn't the most critical. So if that's the only usecase in the wild that got broken, then that might be fine. But I at least wanted to share that others (i.e. me) have used this feature.
