ok, here is what I remember:
I created the patch because I observed a lot of problems with
the --link-pois-to-ways option in combination with the short arc removal. 
This option changes Coord to CoordPOI instances and therefore adds a 
lot of short arcs to rather iunimportant ways, e.g. 
small ways ending on big roads, blocked with bollards or barriers:
As the short-arc-removal algo doesn't care about importance of the road,
it might move points of the big road towards the bollards to remove
a short arc in the small "unimportant" way.
The irony is that many of the small ways are tagged as footways, so
the bollards or barriers should be IMHO ignored reg. routing.
So, I tried to filter those CoordPOI which are added to footways.
While working on the patch I found the errors reg. the maintenance of 
the highway count and also some outaged comments. 
It would have been better to separate them from 
the rest of the patch :-(
