Using "enabled" can lead to confusion—"is the turn 'enabled', or is the restriction 'enabled'?" The word refers more to the state of a control rather than anything in reality.

I don't think so. Try this:

Create a new segment that attaches to an existing segment. It naturally does NOT have and end-node that JNF would add.

Click the junction node where the new segment attaches to the existing road.

DISALLOW All Turns.

Check each of the three segments that No turns are allowed.

Highlight the new junction node and Press Q

JNF "fixes" the unterminated segment even though No Turns are allowed at the connecting node.

I'm not familiar with the old Cartouche interface but, from what I have been able to gather, that interface actually deleted turns when they were disallowed. This could lead to a node with no turn instances at all. And the script needed those turn instances to discover the problem segment. It appears that the current interface leaves disallowed turns in place but marks them as disallowed. Therefore the script has the turn instance to reference and can do its "magic" whether the turn is allowed or now, it's still listed at the node as a turn.

You are right. I've tried your method and it works but I really did face it a few times when JNF did not work when I click the "Q" button. And when I checked, all the turns for that particular node was disallowed. When I allowed one turn, then JNF works.

Strange I'm not facing it now.

Today I accidentally found out I was restricting all turns in a roundabout instead of fixing its nodes. (Running JNF on Tampermonkey on Chrome, LMDE). Now I'm running it natively and doesn't seem to always work (the turns are not denied but the nodes aren't fixed).

Why safer? JNF doesn't make any changes to turn restrictions and only fixes problems.

This isn't actually a good idea. You don't want U turns at the end of dead end roads, generally.

I've seen, personally and in the forums, instances where routing will think going down a dead-end and turning around at the end is better than finding some other legal route.

If you're going the wrong way down a dead-end, Waze will give you a route line and tell you to proceed to the highlighted route, basically.
