You are right I am struggling to find the right term for the common marked
trail tagged by osmc:symbol on relation ...
What you are suggesting?

Might be if having the shape of a symbol.

  - Is best practice to use osmc:symbol to describe the blazes?

It is possible ... it is hopefully clear from the "Values" table and
"Examples" table
Isn't it?

If there is already an  osmc:symbol tag on relation then it is not
recommended to add trailblazed=symbols on way.
This is more precise I believe. You would prefer such a definition?

I've changed this to:

   - Tag trailblazed=no may not be used too often. This probably makes
   sense only when there is blazing highly expected, but not exists.

I definitely agree with you and this is exactly what I am trying to do ;)
Hopefully section "Examples" helping with that?

I prefer answer to the list so others can join the discussion too.
