This is quite insightful, and has driven some curiosity in me and I had to check which exchanges has published their proof of reserve, turns out not many have done this in reality and the leading exchanges seems to take it very seriously, I guess this is to prove the effectiveness of their financial control even coinmarketcap recently announced updated proof of reserve for Bitget which totals $1.54 billion. I definitely will upt in for exchanges that audit their proof of reserve.
