does bluesky yet have a way for users to verify their control of a twitter account, so i can import a list of my followings and auto-follow people here? if not, have they at least talked about methods of converting our social graphs? or do they still not actually care?

Sky Follow Bridge helps you find Mutuals from Twitter. Generate an app password in bsky settings and then open your twitter following page. https://chrome.google.com/webstore/detail/sky-follower-bridge/behhbpbpmailcnfbjagknjngnfdojpko

Not quite the same, but this works decently, especially for people with similar handles in both places
