So it's better to label them all as platforms? I can't see any raised area
in a typical bus stop:

Why would we tag it as if it looks like this?

The section for buses on the main public transport page says: "If there is
no real platform ... the location of the bus stop sign ...  gets ...
public_transport=platform. " I.E. If there is no platform, make one up. How
is that more logical than highway=bus_stop for "there is a bus stop here"?

As for 'why is  a bus stop a highway' do you also suggest we scrap the
tagging for traffic lights, road signs, crosswalks etc. etc?

If tram stops (as described on the wiki) are accessible from both sides and

They are largely imaginary for most types of transport. Most public
transport experiences centre around where the people stand not when the
driver slams on the brakes.

A platform is a platform, a perfectly flat bit of sidewalk isn't.
