However: In general, cookie controls are still entirely there, so I'm positive that specific feature is what they're referring to. I use an extensive cookie domain blocklist and that's all there and functional. (I've never used said "ask me every time" feature in Chrome, but I went through a phase of using that on Firefox.)

UPDATE:
Found the relevant checkin: https://code.google.com/p/chromium/issues/detail?id=51375
Looks like the previous behavior can be re-enabled via the "--enable-cookie-prompt" command line argument.
Perhaps support for re-enabling that by default should go in that bug (or a new one that references it)?
