If only all this energy were directed at helping OSM forwards. We
haven't had a lot of progress in the last few years (I am not talking
about mapping as such, but about the OSM framework itself).
There are still periodical discussions about how to link OSM with
other data sources - OSM IDs are too volatile, and IIRC there were
objections to putting "foreign keys" (like shop branch numbers) into
OSM on the grounds that someone would need to maintain that link. So
how ARE we going to do it then?
Maintenance/verification takes place by those concerned.
If a branch shop number is of concern to you .. then you check it.
The idea that everyone must be able to check everything is ridiculous.
Or are we insisting on building what we in the trade call a "data
island"? Let's build some technical bridges, so it becomes a real
alternative to maintain a parallel data set.
And then of course there are support for 3d mapping and the "area data
type" which have been under discussion for years.
You forgot 'indoor mapping'... :-)
How will we square the circle with regards to data quality?
I've had students trying to square circles .... having shown them how to
square rectangles/squares/triangles on the same machine.
Will the free-tagging laissez-faire camp win, or will the
curated/managed tagging camp win?
I'm in the 'systematised free tagging' camp .. I want a structure that
has a simple good logical basis for the tags. But allows added tags ..
hopefully following the structure present.
At present there is no structure/philosophy that can be followed.
How will this tug-of-war be organised? Will the forces at work cause
OSM to tend to converge towards "quality" or self-destruction? After
all, OSM says its product is the data, not a mapnik representation.
The raster tiles may look OK, but the underlying data may tell a story
of mapnik and OSS-carto having to work very hard to mask bad data quality.
The quality of the data is not your/my issue .. it is the structure of
the tags.
Where is this all going to end?
Aren't there more important things to worry about than whether or not
a couple of hundred ways deserve a place in OSM?

Those who are worried about it .. do it .. and try to fix these issues.
Big issues or small issues ... depends on your view point.
