The plan is contingent upon an extended T5D already outfitted but maybe they do think that is far enough for a person to walk?
Well, I can see it makes sense not to offer a walkway between T3 and T5, given the distance.
The other factor/distance is that the walkway under T5 isn't just there for TTS-dislikers, it's the "way back" without changing sides (twice) if you need to get to a lower numbered (lettered) terminal - eg you have to get from T5D to T5C of whatever (eg if your flight at D get cancelled or you went too far). This doesn't apply between T3 and T5 I guess......
