Well - what if I want to walk around the sub anyway? maybe i dont care wheather real kaluens did it or not.
Real Kaluens didnt work out torpedo solutions, enter data in to the TDC, or man the flak and deck guns either.... yet no one complained about being able to do those things in SH3.
If you want to what a real kaluen did, you would just be deligating most of the time - that would make a boring ass game for sure. (Silent Hunter meets The Sims)
Lest we forget, everyone and his dog begged for fully explorable Uboat since Sh3.
Now we finally get one and it is scrutinized to hell...
