Hmm, I don't mind them, apart from when you load a save you get a whole lot of messages from the previous 5 days or so again.
Also they do give info on historic events like the sailing and sinking of Bismark and the channel dash in which you can then participate or loiter around to see the thing go down.
At some point there will be an interactive sim where sinking or severely damaging HMS Royal Oak when she leaves Gibraltar to catch Bismark will have real implications for the rest of the war.
same goes for SH4 sort of, what would've happened if Indianapolis got sunk before delivering the A-bomb to Guam...that sort of thing
also for general effectiveness of convoy interdiction having an effect. eg less planes around britain because of fuel shortages at the height of the happy times
This sort of thing is already done (but on a larger scale) in many games by Paradox
(Europa Universalis, Victoria, Hearts of Iron) which leads to interesting developments sometimes
