Agree. However I think it would help renderers (and anyone who doesn't
have access to a modest level of pre-processing) if there was a clear
way of:
1) identifying the boarding location
2) identifying a good place for a single symbol/label for a group of
stops (particularly at lower zooms)

I would suggest a much simpler scheme, adding just two new values:

highway=bus_stop_group
railway=tram_stop_group

to provide for explicitly identifying a good place for a single
symbol/label, leaving highway=bus_stop and railway=tram_stop to
identify the boarding locations (yes that means changing the meaning
of railway=tram_stop, but the old meaning would still be valid).

Renderers would then have the option of attaching symbols/labels as
they see fit to:
a) railway=tram_stop, node on a railway=tram way (ie the established approach)
b) railway=tram_stop, node not on a railway=tram way (eg Helsinki)
c) railway=tram_stop_group

{similar for buses}

And before anybody says "tagging for the renderers", I suggest they go
and read the relevant wiki page:
