Looking at the ‘hidden-services’ tag as well:

https://blog.torproject.org/category/tags/hidden-services

led me to this blog post:

https://blog.torproject.org/blog/hidden-service-hackfest-arlington-accords

which states:

| We talked about rebranding the "Hidden Services" project to "Onion
| Services" to reduce "hidden"/"dark"/"evil" name connotations, and
| improve terminology. In fact, [we've been on this for a while][1], but
| we are still not sure what the right name is. What do you think?

I don’t know what the current consensus is though.  I guess variables
with both names should be provided.
