AFAIK, in legacy canvas, it is only a protection against global deletion.
The idea behind this feature was:
* you want to use an external auto-router.
* you can lock all existing good tracks or tracks with constraints.
* you try to autoroute the remaining tracks and import the result.
* If you do not like it, you can remove all imported tracks and retry.
