I fully agree with this argument and I also wrote a comment on the Wiki
Talk page.

What do you thing about using main:forward, main:backward,
alternative:forward and alternative:backward.

Another problem is that whenever there the main trail has a forward or
backward we automatically have two main trails what could be considered as
alternative. However now you can still create a elevation profile from the
main route. One for forward and one for backwards.
