For example, I as a cyclist am not bothered about maxheight=* but truck drivers are. In the past there has been no clear process evident for deciding where to draw the line. If someone wants to create a navigation model for learner drivers, then why not? Who are we to say "that doesn't belong in OSM"? Where are the rules for that? Our job as a community is to guide the development of the tagging so that it is fit for purpose (now and looking into the future) and compatible with what is already there.

Yes, you are right about that (in the case of the UK anyway). So a
"router for learners" should infer the prohibition from
"highway=motorway" or "highway=motorway_link". Motorways (and a couple
of trunk roads) in the UK actually have a funny status called "special
road" - they are not a public highway, and no traffic is allowed except
what is explicitly permitted by law.

I've already encountered roads without a highway tag, but with long lists of foot=yes, bicycle=yes, vehicle=yes, motor_vehicle=yes, hgv=yes, psv=yes, ...

I know what you mean Martin... +1...
