It is in line with BricksForge customizing the client/user experience (like limiting by role, in this case it would be a dashboard page per role for onboarding per role) and as long as the feature is limited to bricks pages it is a helper for Bricks users. If this feature does try to be compatible with pages from other builders (for that the WP Admin Pages plug-in does a good job already) I think it could be looked into as a extension. I would second the request given above limitations and viablity.
From a technical standpoint it would be probably the easiest to load a Bricks page or maybe even template (but a template would be missing a publishing context for ACF etc.) or a custom CPT for these type of pages in a full size iFrame adding a role limit. That would mitigate backend and frontend resources being mixed in the same DOM scope. I haven’t looked into how WP Admin Pages takes care of that “problem”. Just a gut feeling on how it could be achieved without running into unintended side effects hell. From one BricksForge user to another.
There are at least two options, full page replacement and the usual resizable widgets. A third option might be the space WordPress itself uses to announce a new WordPress version (half page on the regular dashboard).
