Documentation on aborting a FreeStyleBuild

I’d like to clarify the documentation on aborting a build.

The documentation states that " * BUILD ID URL/stop - aborts a Pipeline." but “stop” works to stop a FreeStyleBuild (which only calls sleep 100). Should the documentation say that “stop” is supported for FreeStyleBuild?

When I try to “term” a FreeStyleBuild (directly without trying stop first), the HTTP packets send a redirect to “term/” (with a trailing slash) which does not exist and results in 404. I don’t know how to interpret that 404 response from my scripted client. Here is the HTTP conversation:

My guess is: “term” and “kill” are NOT supported for FreeStyleBuilds but are for Pipeline?
