oh okay, I think this can be useful in some cases where we want to avoid data loss similar to its use for physical standby. For example, if the user has by mistake truncated the table (or deleted some required data) on the publisher, we can always it from the subscriber if we have such a feature.

Having said that, I am not sure if we can call it a restriction. It is more of a TODO kind of thing. It doesn't sound advisable to me to keep growing the current Restrictions page [1].
