There's notthing intrinsically wrong with having a segment be part of
multiple ways. It's a but cumbersome, true, but not impossible (you
know the trick to select the way you want when there are multiple in
JOSM? Middle-click then hold down control).

If you don't like that then just snip the way and leave it to the
renderers. They're slowly getting smarter and in time this problem
will not be so bad.

To be honest I think it's crazy to have a tag with so much intrinsic
meaning as ncn, it looks useless outside the UK. There should have
just been a cycleroute tag that people could extend. In any case, the
way to extend it has not been standardised so you can do whatever you
feel is appropriate...

Have a nice day,
