yes, topic/post ID is easily obtainable if one needs that. The only thing is to make topic and post ID search friendly via specially designed keyword - t:2075 as you have suggested.
I’ve tried both from share and timestamp (desktop) and shows only part of the url without ID, while touching the timestamp on my iPhone/mobile safari shows the part of the url with topic/post ID in it. Link shown in share box is fixed, I can’t move cursor further. But that’s ok since ids are shown in url and user with enough brains can figure it out. I’m just talking about the id search feature.
