I discovered my crank was same when I stripped it 7 years ago, and in addition the shaft was worn, which only became apparent when I was shimming it after a re-grind...the main journal has a well-made sleeve over it, so not obvious until it dislodged when pulling the bearing off a second time....
With very little options and already in deep, I shimmed it out and loctited the sleeve gone with it, ~ 12K miles later is hanging in there, but I don't flog it (I think)..
Not ideal, but you may have better resources available to deal with it. good luck
