<div dir="ltr">Hm... it's a different subject... but it's much, much more than ordering. Edits to ways: splitting, lengthening, shortening, combining, adding and removing, can destroy many routes of different kinds, not only unordering them but making them unorderable because of duplicate ways, branch ways, interruptions, faulty roundabouts, breaking roles and turn restrictions. I'd rather see newbies making mistakes and make them correct those mistakes themselves, than keeping them away, ignorant and a permanent newby.<div><br></div><div>But in the end, we should think of a way to prevent this from happening altogether.

<p>I prefer that those complete newbies get to mess with only 1 or 2 members of route relations, at the relatively small price of ordering.</p>

The majority of edits to relations involve downloading only <br> 2-3 members. If only 1 member is added or removed, that's how they <br> become unordered.<br> Personally I'd prefer it stays like that, because I've seen complete <br> newbies make some really weird edits to cycleroutes, because they <br> obviously didn't understand what it was.<br> > <br> > _______________________________________________<br> > Tagging mailing list<br> > <a href="mailto:Tagging@openstreetmap.org" target="_blank">Tagging@openstreetmap.org</a><br> > <a href="https://lists.openstreetmap.org/listinfo/tagging" rel="noopener noreferrer" target="_blank">https://lists.openstreetmap.org/listinfo/tagging</a><br><br> _______________________________________________<br> Tagging mailing list<br><a href="mailto:Tagging@openstreetmap.org" target="_blank">Tagging@openstreetmap.org</a><br><a href="https://lists.openstreetmap.org/listinfo/tagging" rel="noopener noreferrer" target="_blank">https://lists.openstreetmap.org/listinfo/tagging</a></blockquote>
