I also asked about this here, as a part of the issue rename to work, but Jira projects seems to have been the real misnomer (long been used with a lot of muscle memory). Not sure of the best way to solve it.

Even though a ton of work for me and others, seems like they both could use a rename. Jira projects to space or workspace maybe? And Atlas projects to segment or stream or milestone or initiative or program or loop (to tie into The Loop concept, but that it really on the goal/OKR level too)?

Atlas "project" makes sense but will just continue to get confused with a Jira project (incorrect terminology, but been around forever).

Thanks for raising this issue.

It's not just Jira projects vs Atlassian Home projects, but also our internal business projects, which we have a bespoke issue type above Epic that we use to manage projects with 'project' in the title.  The work within these 'projects' is managed within one or more Jira projects. In addition other parts of the business have 'projects' which are managed less formally via 'Epics' within Jira projects.
