That's indeed an interesting discussion to be had. I think at some point
a while ago (I might be wrong though) it was suggested that per default
Activities should be shared. I guess such a behavior would then also
apply to all within an Activity tabs.
(Not that I neccessarily think that sharing be default is a good idea...)
