The notion of current project is very common in most editors, so I imagine this will be TRT, sooner or later. Not that I'm in a hurry for that. >> Another long-term violation of your idea is the default definition of >> xref-backend-references. It uses the current project.

The use case is 'M-x xref-find-refereces' and xref backends which don't override xref-backend-references. In which case this command searches the current project using general purpose tools (one of semantic symref tools, or Grep). But xref backend != current project. They're technically and theoretically independent.
