Thank you for pointing me to that discussion, very interesting. However, it seems that the discussion is still ongoing. When a conclusion is drawn, yes, this route can be "nomalised".
My focus on this route has been to update the route relation to reflect the new route, but I did not put much energy in the route metadata.

Hi, thanks for your interest and question.
According to the via-alpina.org website, the old trail system is replaced by one route in 2024. I have had contact with them by email, in which the message was the old routes are still mostly signed, but will not be maintained. Signs will be removed in the coming months/years depending on a lot of factors. They do not recommend the old routes to stay on OSM.
My thought was, to avoid people to start adding the old routes again as long as the old signs are still up, to put the old Red route (superroute and not-used red stages in the new route) on disused:route=hiking. Maybe next year the old routes can be removed altogether (?). The other colored routes (red, purple, yellow, green, and blue) should also be set to disused, if this method is to be followed.

I have received an answer from Via Alpina.org. The old routes are still mostly signed, but will not be maintained. Signs will be removed in the coming months/years depending on a lot of factors. They do not recommend the old routes to stay on OSM. To avoid people to start adding the old routes again as long the signs are still up, I decided to put the Red route (superroute and not-used red stages in the new route) on disused:route=hiking.

Yes, at the moment I'm doing remote mapping. Thanks for your concern to keep confumsions at bay. I have reached out to via-alpina.org for clarification of the signage of the old an new trails. For now, I would like to get a baseline of the new trail in OSM. Changes to it according to signs will come when people start walking it again during the summer months. I'm just working on the route, not actual position/layout of paths or streets, so Lidar data does not seem helpful to my process, but you do you! If I receive more info from via-alpina.org I will post here.

Yes, it should have been "VA-R1".
I'm not affiliated with via-alpina.org, all I have is the info on their website. Unfortenatly, it does not mention anything about old/new/updated trail markers. My working assumption is that the old trail markers are still there, so I leave the old route in tact. I reference the GPS traces on the map of via-alpina.org with the old stages, and if there are differences I make a new route (also, I do not know if the route and/or signs have been updated or if they just took a wrong path). If you would like to help cross-checking the GPS traces, start at the end, and we'll meet in the middle; if not, also fine.

Dank je wel voor de feedback.
Ik had ergens gehoopt JOSM voorlopig nog te mijden, maar als ik er toch niet aan ontkom, dan ga ik er maar mee aan de slag.
Dank je voor de links om met JOSM te starten...

Dank voor de uitleg. Ik heb dat op een paar andere punten dus niet volgens deze conventie gedaan en zal dat daar rectificeren.
In dit specifieke geval vroeg StreetComplete of dit een eenrichtingsweg was vanwege de smalheid van de weg.

Dank je voor de input!
Soms lijkt alles zichzelf te wijzen, maar moet ik toch nog wat meer tijd op de wiki doorbrengen.
Thnx
