The requirements permissions option gives more permission than some users should have simply because they need to use the map button. Additional options are needed to refine capabilities beyond delete.
The Jira requirements option is the best example as to why this feature is needed. Only select people should be able to bring in requirements, but more people should be able to map.
The proposed change (feature request) would offer more options as follows:
1) Read only (includes Export Requirements, map button)
2) Read/Write Only
3) Read/write Delete (with Jira Sync config, Jira sync Requirements, and disable sync)
