Yes, at some point, this idea was experimented with in 0004-Expose-progress-for-the-vacuuming-indexes-cleanup-ph.patch. This patch did the calculation in system_views.sql However, the view is complex and there could be some edge cases with inferring the values that lead to wrong values being reported.
