That is a fair point.

And the lack of documentation and the fact that the code is not yet
considered stable enough is the reason why it's not in-tree.

I guess that the test-runner can be put into a separate git repo, it
does not depend on the rest of the LTP in any way, which should make it
easier to get the source code, without pulling in the outdated LTP
repostitory.

Also the local test execution is called shell backend, in that case the
testrunner forks a shell instead of doing a ssh connection and executes
the testcases locally.
