Your personalized whitelist is about 30k. Would it help if brainstorm were to make some smaller personalized lists available? How about your top N pubkeys, not all 30k? Maybe top N, next top N, next top N, etc? Or how about top N pubkeys but not including pubkeys you’re already following? Which would be a way to discover novel follows.

It would be relatively easy for me to add these lists to the API so relay tools could download them.
