Um, I've been having some difficulty following this discussion. Would someone be so kind as to explain (perhaps with a small example) the conditions under which this patch would be useful? I'd be most interested in trying this out, if only I could understand it. ;-)
highway=* & cycleway=opposite { set oneway=-1 }    [0x01 road_class=0 road_speed=0 resolution 24 continue]

This example would allow you to put an opposite cycleway with your choice of speed. The current --make-opposite-cyclways however uses the same speed/road_class as the road it is on. I as a cyclist would like to avoid, but not block going against the usual flow of traffic. with the above only in case nothing else more or less is possible I would be routed against traffic direction.

There can be plenty other things you could use this for (also for example setting different road_class / road_speed for one type of street depending on mode of travel by setting different restrictions).

Note however that it only works 100% well, if you route over the oneway (or whatever you choose to change) street, not if you have a route ending there or starting there. That is a limitation on Garmins side however.

You could also say, I as a cyclist don't respect oneway at all, so lets put

oneway=yes | oneway=-1 {set oneway=no } [0x01 road_class=0 road_speed=0 resolution 24 continue] - so usually you should not be routed against oneway direction, if there is a significant shortcut you will however.
Cheers.
