This is problematic as some regions do not use cycle nodes yet.
I don't see why rcn routes have to absolutely be with cycle nodes.
Regional roads are still regional, even without cycle nodes.

The Brussels Region network makes a difference between ICR/GFR routes,
local routes and themed routes, with the addition of national routes
(like RV1, RV10, LF2 or LF56). That's 4 possible levels.

- ICR/GFR routes link the center to the border of the region and
regional routes, or go in circle in the region. I guess the regional
routes these connect to will be with cycle node when Flemish Brabant
has them.
- municipal routes are mostly within a single municipality and connect
ICR-GFR routes.
- themed routes either go around green areas or along former train
tracks. The Green Path goes around the region through marked tracks,
lanes or regular streets.
- LF, RV and Ravel routes actually go beyond region borders. Since
there is no proper national network, it makes sense to use ncn for
those.

The difference between ICR-GFR and local routes is arguable so I see a
point to tag ICR-GFR as local routes. As a matter of fact the Carte
vélo/Fiestkaart just uses the same colours and tags, local (i.e.
municipal) routes are labelled G/C whereas ICR-GFR have proper names
(1 to 12, KC, SZ, MM and PP after the recent update). So tagging
ICR-GFR as lcn makes sense.

However this makes less sense if themed routes are also tagged lcn.
Meaning, it is hard to make the difference, except for the labels.

I just defaulted to rcn for ICR-GFR, just like we defaulted to ncn for
LF/RV. I'm not yet convinced lcn is better, it is as good I think.
Using rcn offers the choice of using lcn for themed routes.
