We currently have a method on our store spi to control writing to a store if certain flags are set (currently only used by rolling upgrades with RemoteStore). https://github.com/infinispan/infinispan/blob/8cfcf3a0c2ca30a7e7e3815d299253ef8c652756/core/src/main/java/org/infinispan/persistence/spi/FlagAffectedStore.java We should figure out a better way to handle this before we remove Experimental tag from the new SPI.
