This is to be expected. You are kind of spoiled because during the last
year this is about the only larger technologically more sophisticated
change in the style.
Discussion of this change can be found in:
and discussion leading up to this in:
The reason for the technological complexity of this and the resulting
mangling of the code is the lack of support to render lines with a 2d
pattern in Mapnik.
I still hope Lucas will write up a few details about the technical
approach that would enable you to more easily re-implement this in a
Note there have been voices to choose a more conservative approach to
rendering unpaved roads in OSM-Carto - like yet another form of dashing
in addition to the various dashing types already used in road
rendering. There are very good cartographic reasons not to do that
All in all this is a good example for OSM-Carto being at a crossroads
(and having been for quite some time) between staying avant-garde and
pushing the boundaries of cartographic design and technology or being
satisfied with shuffling the options offered by the cartographic
mainstream within the technological framework used - and which, due to
Mapnik and CartoCSS being essentially unmaintained, becomes more narrow
and limiting every year.
