There were a couple of reasons for the removal, but the primary reasons were: it has never worked very reliably (it was not a 'last active' timestamp, it was a 'last triggered an unreliable login-related event' timestamp), and there were some legitimate privacy concerns around it (especially since there was no 'choose to be invisible' ability).

That's not to say we can't see how it could be useful - but the above concerns outweighed the benefits of keeping it.
