Should `system_dependencies` allow self referencing?

Is your feature request related to a specific problem?
Systems can send data to themselves, so is it useful to be able to list themselves as system_dependencies? Right now it is not possible. system_dependencies is deprecated, but egress and ingress are replacing it and do allow self referencing. Making this issue as a place to discuss the pros/cons

It's very unlikely that any changes will be made to the system_dependencies implementation, other than to remove the field in a future version of fideslang (see #86).
Separately, whether or not self-referencing should be displayed in a visual datamap is unrelated to the implementation detail of whether or not self-referencing should be allowed in egress and ingress DataFlows. The egress and ingress fields are intentionally permissive, so any limiting of displayed data should be discussed as part of a front-end-only change, or it may be worth discussing that as part of a design discussion.
I'm closing this issue because no code changes will come out it.
