Yes, what I have in mind is a new primary tag:
`highway=scramble`
with secondary tags like
`scramble=via_ferrata`
`scramble=climbing`
`scramble=alpine_hiking`
etc.
Tertiary tags would be:
`via_ferrate_scale=*`
`climbing:grade:uiaa=*`
`sac_scale=*`
The secondary tags would be orthogonal. In case of conflict, the most
common use of the scramble should be tagged. The tertiary tags can be
used side by side if applicable.
-----------------
*Implications for data consumers*
`highway=scramble` for data consumers basically means:
1a) Don't render this as normal paths.
1b) If you do render it, render it differently.
2a) Don't route pedestrians along here.
2b) If you do want to route specialists here, then have a look at the
secondary (and tertiary) tags.
-----------------
*Obsolescence of other tags*
This would mean that there is a new primary tag `highway=scramble` which
makes some currently existing primary tags obsolete:
1) `highway=via_ferrata` gets replaced by `highway=scramble +
scramble=via_ferrata`
2) `climbing=route` gets replaced by `highway=scramble + scramble=climbing`
3) Paths on the difficult end of `highway=path + sac_scale=*` get
replaced by `highway=scramble + scramble=alpine_hiking + sac_scale=*`
(exact difficulty threshold to be discussed, see below).
-----------------
*Detailed definition(s)*
This is just a coarse sketch.
If it gets any support, then yes, the details would certainly need to be
thought through and discussed:
- What's the exact scope of highway=scramble? Does it include caves or
tunnels where you have to crawl? (I'm sure there are many other examples
that haven't been mentioned yet)
- What are the exact thresholds between path and scramble?
- What counts as special equipment?
- etc.
I suggest we first decide whether we find the general concept of
highway=scramble to be useful and want to introduce it at all. In case
we answer this positively, then focus on working out the exact details
like what's the exact sac scale threshold, etc.

To me, highway=scramble seems a good solution for this, but I'm not a native
English speaker, so there may be better terms that I'm not a aware of.
just to get it right, you are suggesting to deprecate highway=via_ferrata in
favor of highway=scramble?
AFAIK climbing routes aren’t currently tagged as highways, why would we want to
have them in the same category as hiking paths?
Is a torch qualifying for special equipment? E.g. paths in caves that aren’t
lit?
What kind of shoes would you consider special equipment?
Is special equipment and extraordinary courage a requirement that is relative
to local habits or is it to be seen on a global level?
