Current usage: https://taginfo.openstreetmap.org/tags/highway=trailhead

Overpass shows most usage is in the US, Canada and Japan, now also
Nederland, and some in Italy.

highway can be applied to nodes and ways, and it compares nicely to
highway=bus_stop. A trailhead is then seen as a "trail stop" for trail
"passengers".  I think that's why it was chosen in the trailhead proposal.
I saw no compelling reason to change that, even though I can see your
argument to use tourism=.

Advantage of highway= is that you can still add the tourism= key for an
information board if it coincides with the trailhead.

Do you see an actual problem with this usage?

Lots of places give access to trails, of course. But if they are not
visibly designated/designed and operated (not just picked!), I would not
map those places as trailheads. No one has to do that. On the other hand,
in other countries useers may see fit to map those kind of locations as
trailheads, because they want to search/list them and see them on a map.

Given that the Dutch community has a very specific definition of

I fear that this would cause more confusion than it solves! I would like
not to go principle and exact definition about this, and just take the
practical approach: If a place fits the very general description I
suggested, then if a mapper sees fit, (s)he may use the trailhead tag. I'm
sure the local/regional community will moderate if necessary, to ensure the
tagging fits their situation.
