"Blaze" also seems more consistent with:

But I agree with you, "marker" sounds better and could cover more cases.

Maybe, we could use "marker" as a role in the route relation describing
the hiking trail. Each trail_blaze node would be member of the relation
with the role "marker". Is this fine?

I initially suggested to use this key on the french mailing list. I took
my inspiration from:
http://taginfo.openstreetmap.org/keys/support#values
It is very possible that this key made sense to me because of the
similarity with the french word :)
