The hasselt osm file is sime 12 MB, the colorful hasselt pdf file just below 1
MB so that's okay (3.7 sec processing time on my machine so if all claims are
right sub seconds on a fast new apple).
I finally tried this, hoping to replace my Maperitive workflow.
With a Bonn map from https://download.bbbike.org/osm/bbbike/ of 724 MB I
started it last night (~13 h before), and it still didn’t finish. No messages
after:

openstreetmap > original size 713811948 bytes, stripped down to 603309215

Maybe I should try smaller files ;)
Indeed:

The PDF is 488 kB.
Redefining color works, if you know what you’re looking for – and it’s partly
really strange what is marked how...
Seems like I should start to work on OSM again.
yes, and we need to add more heuristics (i already added some after
rendering don knuths university site (apart from the many fast food
venue research institutes are also marked 'interestingly')
Are there any plans for text labels, e.g. street names? (I guess these are
really tricky.)
depends on how
