Please don't make things more complicated than they need to
be. Most <br>
hiking routes are just a single relation and are best left
that way.<br>

No. Don't assume that route ways are sorted in OSM as they
usually aren't.<br>

<div>I know, and it's a pain. If software could easily sort
it, fine but it can't. That's why things that break sorting
should be avoided. </div>

Pretty much irrelevant. As long as the data's there,
software can <br>
figure it out.<br>

This depends entirely on the use case. As an example, it is
for me.<br>

<div>I mean, the rendering can be critical for the use case,
but the order and consistency of the ways is usually not
critical for useful rendering. </div>

It can be critical for routing. If a route uses a single way twice -
once forwards and then backwards then the order of the route can be
hard for a computer to figure out. <br>

<div>If it is in your case, you would have problems with lots
of routes, because almost all routes I see are damaged in a
few places. If I repair it and come back two weeks later,
same thing. <br>

<br>
Yes. <br>
<br>
Even more so for admin boundaries the use roads. The roads get
edited and that editing brakes the boundaries. <br>
