Non-motorised access is allowed anywhere in Scotland, with some exceptions, per the Land Reform (Scotland) Act 2003 - the fact a path is a core path has no bearing on this. The particular aspect of the access tag which I considered to be inappropriate was 'bicycle=yes', since these are informal unmade paths on private ground. I therefore judge it to be inappropriate to have them appear as cycle paths on maps, since this encourages cyclists to use them, and tends to imply that they are suitable for general use by cyclists. I would argue that it is better to tag these ways as paths and leave the access tags ambiguous than have them appear as blue lines on cycle maps. Having said that, do feel free to revert the changeset if you disagree - I won't be offended ☺️
