that wikipedia page is quite messed up by an recent edit war about
the use
of "free climbing" in different parts of the world, the current version
is historically wrong.
Certainly, it doesn't match the historical use in my country either.

You might even add a converted grade (although the conversion isn't
unique since 5.13 might be anything between 7c+ and 8b):
No! Conversion of grades is subjective and can be done by the
data consumer. The grade should be in the native system of the
area. We also do not convert maxspeed=15mph into km/h tags, since
that can be computed.

Sorry, I wasn't specific enough here; I meant if there is an official
converted grade.
In my area the guidebooks usually have two grades for each route;
Norwegian grades and French grades. In such cases, when there is an
"official conversion" (but doesn't really match the conversion tables
on e.g. the wiki-link above [1]), I think both can be added.
Adding data from guidebooks is not acceptable, they are copyright.
This has always been my concern with climbing routes, ground surveying
can show locations, but when I used to climb all grades and route
details came from a copyright guidebook. A mapper who has made the
climb and assessed the grade personally can add this, but will this
normally be the source?
Sure, one would need to check the copyright before taking *any* info
from the guidebook (name, grade, etc.).
I am one of the editors of the local guidebook, and the main editor
asked me to put the crag info into OSM.
I haven't mapped any routes in OSM though, just crag info (so far).
