I wanted to start my own topic one day, but I feel that you have touched
very important and general problem related to rendering, which is
amplified by current changes authored by Mateusz.
We have very uncomfortable situation with rendering styles on our main
website: out of 5 styles available only 2 are general, and only one -
default one - is to some reasonable extent an OSM community effort
(technically it's open, in practice not much people are active there, it
is rather detached from other parts of OSM and is rather conservative
socially). HOT is kind of a special task force and community in itself,
as far as I understand, so I don't count it as a general style.
Goals of default style are also non-uniform:
https://github.com/gravitystorm/openstreetmap-carto/blob/master/CARTOGRAPHY.md#purposes
which makes it even harder to deal with.
It was just a matter of time if someone will try to make some bigger
changes, which will result in explosion. And here we are...

My point is: we - as an OSM community - need more styling options,
because default osm-carto style is unable to effectively take all the
responsibilities and expectations.
There are many solutions to consider. All of them have their strengths
and weaknesses, in short they can be:
1. osm-carto-devel, which can be visually less elegant, but more
intended for the mappers to see their work. However it means double the
resources we use today, so this may be hard to achieve.
2. Layers like http://osm24.eu/ (POIs with opening hours) or
http://osmapa.pl/w/area/ (highway:area=* test rendering), which are much
lighter than full style - however they don't blend with underlying style
seamlessly.
3. Vector tiles, which allow having plenty of styles available and high
personalization, but on the other hand deserve additional infrastructure
(I guess less than with osm-carto-devel?) and are probably much slower
to render, because it's done on the client side.
I believe 3. is the future. We won't be able to serve every possible
style in any other way - be it UK, US, but also with local names in
every language etc. It will also allow people to learn styling and
enhance our collective skills in this regard. But maybe we could also
use other styling options in the meantime.
I also think about adding additional features, like support for umap (
http://umap.osm.ch ), which can help some users to create their own
small maps based on OSM, and indoor or even 3D viewer included on the
main website (think about multi-level malls and railway stations - they
are unreadable today).
I don't know how many resources we have to extend current situation, but
rendering maps is simply too important for the people to live with just
one general purpose style influenced by the community.
