Hello,

I am afraid this changeset introduces arbitrary restrictions.  Under Belgian law, cyclists are not required to use cycle tracks or lanes if they change directions.  

Here is a concrete situation: https://www.openstreetmap.org/way/23598324
A cyclist coming from the north may want to stay on the carriageway to enter the roundabout and make a left turn towards Is. Meyskensstraat.

By setting "bicycle=use_sidepath", you instruct navigation engines to no longer use that road.  Those engines will no longer offer this possibility and will force longer detours.

This is the reason why we always examine the routing graph instead of blindly applying this tag on any road with a cycle track nearby.

Could you please enlighten us about why you felt it was important to use this tag?  Did someone request to do it?  Is there something special here explicitely forbidding cyclists to enter the roundabout?

Thanks in advance.
