Personally, if I wanted to see my Hiking activities in the reports, I would simply record them as Walking which they are anyway. The activity profile Hiking is comletely redundant, and probably kept ony for historical reasons. I never use it even if I hike. The Walk Activity profile does all I need.
Only because YOU are don't need a hiking profil, does not mean, that nobody wants it. Some people like to differentiate walking from hiking, because it does have different context to them. So maybe let them choose and wish what they think is important.
