As much as I'd like the game to take a slower pace, I'm sure this isn't going to happen and I sincerely hope so. FD just added telepresence because they figured casual players would be put off by having to fly their ship to a certain location and not use it as a result - what makes you think they'll ever add anything that slows anything down?
In the case of 2.3 I don't have a strong opinion. I can perfectly understand people won't coordinate and fly around for 20 minutes just to be play a third person rail-shooter or fly a fighter for a few minutes. I wouldn't do it myself, but don't care because it won't affect my gameplay at all.
The best I can hope for with walking around is FD keeping it purely optional just as crews. In the case of walking to take a mission, I'd be opposed because it doesn't add any gameplay. E.g. I'd be all for real-time ship repairs because although it wouldn't add gameplay, it would enable interesting decisions and thus could add depth to multiple ship ownership.
Can't see either for walking around.
(On a side note if you want to reach the coffee machine, get a Vive, however reaching it isn't all that spectacular
