My two cents:

tl;dr: Leave it up to player preference.

The history tab doesn't hurt anyone, but those who let it hurt them.

Taking it out doesn't make metagamers less metagamey, lol. At the end of the day, if you're a metagamer, you're still going to find a way to metagame in some way.

Also, sometimes I wonder, maybe people don't fill out the history tab, because in reality. Their characters are just walking carbon copies of one another with no real substance or background to them? Perhaps they want you to "Ask ICly" because they're pulling their "terrific" backstory out of no where.

And I can't tell you how many times I've forgot relevant IC information about a character I use to RP with from extended absences. And you know what? It makes RP go by a bit more fluidly if I don't have to pause the RP, break character and go,"Wait, does my character know X?". Maybe it would be nice to collapse the History tab into a conglomerate "Other details/Backstory" tab. But other than that, I think it should really be left up to personal preference.
