In the situation that a trailhead node represents a named cluster of helpful facilities/amenities in the vicinity of several trails or networks, you wouldn't want to add it to all the relations, because a. it's not actually part of the routes and b. maintenance of all the routes would be quite error-prone and not really intuitive.

At the risk of repeating myself:
I think I'd need more concrete examples before I'd support such a
proposal. I think that we have people in this conversation with
different cultural expectations of what a 'trailhead' is. My
northeastern-US definition is, "anywhere that you get on and off a
trail", so usually there's parking, and perhaps a notice board or a
register book to sign, but I don't expect many more amenities than
that, and sometimes not even those. It may happen that a trailhead is
in a developed facility in a park (such as a ranger station,
recreation ground, campground or visitors' center), or even in a
populated place, but in that case I think of the amenities as
associated with the other facility and not with the trailhead.
(Except, of course, for the trail-specific ones such as notice boards,
signposts and registers!)
If what's under consideration is 'a NAMED place to get on and off a
trail,' then I know of only a handful of trailheads anywhere me that
have names other than the names of geographic features that they're
near. (The "Route 23 trailhead" or the "Roaring Brook trailhead" are
typical - they are simply informal descriptions, not real names.)
There are a handful of exceptions, like 'Sled Harbor' (near 42.5237 N
74.5629 W) or 'Elk Pen'
(https://www.openstreetmap.org/node/1305445030) but they are actually
described well by place=locality, since they name the place, not the
trailhead. Historically, Elk Pen was where rail tycoon E.H. Harriman
kept the elk for his private hunting preserve, and Sled Harbor was
where loggers stored their sledges in the summer months. 'Named
uninhabited place' is a good description of these.
If 'trailhead' degenerates into 'any intersection of a trail and a
highway' (which is what it is in that National Park Service database)
then it's kind of redundant. It appears to me that the Europeans have
a more specific idea of what a 'trailhead' is - but I don't quite
understand that idea, and I suspect that's because there are no
trailheads of that sort near me, despite the fact that I'm within an
hour's drive of hundreds of hiking trails, including a handful of 'big
name' long-distance ones.
I'm not against the proposal, necessarily, but I'm far from convinced
that everyone is reading from the same page, and I'd like to avoid the
risk of a false consensus.
