If my theory is correct, then your current backlink profile is irrelevant because google has your backlink profile in history and to them that is more important

.

If you manage to get a lot of old backlinks removed, especially backlinks from a number of different domains, that could indicate to Google that they were under your control, and strengthens the evidence that you did some artificial link-building in the past.
