Although the documentation says: https://github.com/mapbox/simplestyle-spec/tree/master/1.1.0 maki icons will be supported as markers, there are some maki icons not supported.
e.g. mountain, which is essential as there are many articles on mountains and this is the natural icon, I guess.
(same for volcano, stadium, castle)
See https://de.wikipedia.org/wiki/Hilfe:Kartographer/Maki_Icons#/maplink/0 for the gaps. (generated with <maplink> iterating over all the icons)
It seems like [[ https://github.com/mapbox/makizushi | makizushi ]] is only worried about mapnik upgrades and it's becoming deprecated. Therefore, [[ https://github.com/mapbox/makiwich | makiwich ]] is going to be the successor map marker creator.
With the current stack is not possible to have the latest [[ https://github.com/mapbox/maki | maki ]] running, unless we migrate to libraries that use `makiwich`. That is also a problem because we have third-party libraries relying on makizushi, like `geojson-mapnikify` which is a dependency for `tilelive-overlay`, and they are following the same path as `makizushi`.
It's a considerable change of codebase that we are not able to work right now.
