I just wanted to share an interesting paper about contact discovery and how to do this privately:

Start by reading the three linked papers on private contact discovery at scale. The issue does not identify a Matrix specification section, a concrete protocol change, or acceptance criteria, so a contributor would first need to clarify the intended proposal and define what completion means.
