as I wrote on the talk page I am fully in support to update the proposal to include modern tanks and other relevant vehicle types. > As we are generally rejecting subjective tagging like suitability and the > like, this practical speed tag does not fit well in our system It just fills a gap. Many other tags such as track type and even highway type (primary/secondary...) are highly subjective and used very differently from country to country. There is no reason to think track types are any more objective than maxspeed:practical. Just tagged a road in the Seychelles as tertiary.. I remember it is a slightly difficult single lane partially paved road with a steep incline in some places. Even if I would remember every single detail of the road and use all existing tags - what can you deduce from that? What can routing software deduce from it? If I add maxspeed:practical=25 everyone from anywhere in the world has a first idea what to expect. Even if people would argue that it should be 15 or 30 instead of 25, all other tags taken together are not anywhere close to help you predict a similar value.
