I'll grudgingly nod my head at this. But, especially in recent versions of
JOSM (and one should always be using the latest version), I'd say this sort
button gets it right 99.99+% of the time. Again, IMO, but what this means is
that clicking the sort button in JOSM's relation editor as the last thing you
do before closing the relation ("saving" it into JOSM's about-to-upload, but
haven't-yet "buffer") is a highly recommended behavior to get into the habit of
doing. Highly! It REALLY "neatens up" any route relation, and always reveals
gaps, an error (however slight) in any route relation. I have constructed
literally thousands of route relations over 13+ years in OSM, maybe 90+% using
JOSM (say "yuk!" to relation editing in iD!). JOSM's sort button is a highly
valuable step to both learning how to and actually MAKING relations be
well-constructed (route relations especially, but multipolygons as well).
Doing so will accelerate the practice it takes to do this, making the sort
button a valuable pedagogical tool for route relation construction (good
habits).
Any vanishingly small chance clicking sort doesn't always "get it right" is so
small as to be well worth taking. It's OK to not get it 100% correct "this
time" you close the relation editor window, as long as you are committed to
coming back and making it better later. Editing relations in OSM (even using
JOSM) is difficult (especially at first): there is a distinct learning curve
and anybody who does it should allow this. (But don't be TOO sloppy!)

There are some OSM editing-habits which are forgivable. As JOSM has what can
be a pretty steep learning curve, this can be ("short-term") forgiven, if the
finish line includes eventually "doing it right."

I don't think there are significant differences between these, so yes, that's
sensible. But hiking routes, as noted, are a notorious exception with
carefully-tailored role tags which, where applicable, must be used in this
specific type of route.

I think so, too.
