Let's restart this with some basics.

According to Wikipedia:en <https://en.wikipedia.org/wiki/Bus>:
" A *bus* (contracted from *omnibus*,[1]
<https://en.wikipedia.org/wiki/Bus#cite_note-EB1911-1> with variants
*multibus*, *motorbus*, *autobus*, etc.) is a road vehicle
<https://en.wikipedia.org/wiki/Road_vehicle> designed to carry many
passengers <https://en.wikipedia.org/wiki/Passenger>."
with the possible subclasses:
" Buses may be used for scheduled bus transport
<https://en.wikipedia.org/wiki/Public_transport_bus_service>, scheduled
coach transport <https://en.wikipedia.org/wiki/Coach_(scheduled_transport)>,
school transport <https://en.wikipedia.org/wiki/School_transport>, private
hire, or tourism <https://en.wikipedia.org/wiki/Tour_bus_service>;
promotional buses may be used for political campaigns
<https://en.wikipedia.org/wiki/Political_campaign> and others are privately
operated for a wide range of purposes, including rock and pop band tour
vehicles"
The official German term is "Kraftomnibus"
<https://de.wikipedia.org/wiki/Omnibus>
(according to the German version of the EU documents)

Unfortunately in OSM the term "bus"
<https://wiki.openstreetmap.org/wiki/Buses>is used for public-transport
buses only:
" *Buses*, *coaches* and *trolley buses* are forms of public transport
<https://wiki.openstreetmap.org/wiki/Public_transport> that operate mainly
on the road network. The system consists of bus routes calling at bus stops
and bus stations and have a number of related features."
(also to note that in OSM "coaches" are included in the category PT-bus)

And (answering to another question somewhere in this discussion) there are
cases where we need in OSM an access tag for these generic buses, for
example to map the access restriction announced by this road sign
<https://de.wikipedia.org/wiki/Bildtafel_der_Verkehrszeichen_in_der_Bundesrepublik_Deutschland_seit_2017#/media/Datei:Zeichen_257-54_-_Verbot_f%C3%BCr_Kraftomnibusse,_StVO_2017.svg>
.

Given the orginal "sin" of wrongly limiting the term "bus" to
public-transport buses in OSM (which I believe cannot be undone), we need
to sort this out by creating other terms.
I have no proposal for this, but the original proposal of defining
positions where non-PT buses load/unload passengers is basically a good one.
The real problem is to properly define different classes of
mulit-seated-motor-vehicles-with-more-than-8-seats, and then revisit the
existing tags accordingly.

Regarding "bus" stops:
PT-buses in many countries have reserved stop locations, where non-PT buses
cannot stop.
In many cases PT-bus stops are reserved for buses of specific operators.
And I think (to be verified) that Flixbus is a long-distance PT-bus
network, that does not stop at PT-bus stops, but in other locations, often
shared with non-PT buses.
I am sure when we look closer at different countries we detect all kinds of
hybrids.
One, which I know first hand, is an on-demand night-bus system (in Padova,
Italy)
<http://www.padovanet.it/notizia/20190318/night-bus-nuovo-servizio-di-autobus-notturno-chiamata>
that is operated by the company that runs the city's scheduled day-time
PT-bus lines. This night-time on-demand service has no fixed routes but
allows pick-up/set-down of passengers only at the stop locations of the
scheduled service.
