since the pool still tells the worker whether or not the share was accepted.
Which is related to new _bitcoin_ block, not _pool_ block. No useful info here.
person's share count isn't secret information. Taking it out just frustrates honest people tweaking/monitoring their legitimate miners.
It is. Nobody than miner and pool know how shares he submitted. And once miner don't know when the round ended, he cannot tell on which round he's working. Also as I said, some kind of share counter will be back soon, to allow miner checking by user.
I don't really care about what information is on the statistics page, though, since I don't check that very often, but taking out the current round duration is another piece of easily-obtained information: (Current Timestamp)-(Timestamp of last round ending)
Timestamp is simply current time, nothing about round duration.
I don't understand pool cheating all that well
This explains a lot

you could put the estimated reward back in
Will be back soon, please be patient.
