Well there's no need to suppose. While I think if it hasn't been exploited in 30 years, there probably isn't an attack surface, you can always demonstrate and report an exploit.
I dont think its highly exploitable, but you could get people in trouble - have them visit innocuous website during a vulnerable time window, spray a bunch of adult websites into their history, report them to the boss, future visits do not inject history items.
