We recently added the global KeySet that every plugin has access to. We could use this to pass additional information to plugins from kdGet and kdbSet. For example we could add system/elektra/placement to let plugins now, in which placement they are currently being called. This improves plugins that are mounted in multiple get/set placements (such as list), because they would know whether the current call is e.g. pregetstorage or postgetstorage.

This would also make it possible for a plugin to be a resolver and storage plugin simultaneously, which would e.g. be helpful for specload.

Thank you for adding this proposal! @mpranj and I already discussed it (even how to do it efficiently by simply copying metadata instead of creating new keys for every plugin).
