Certainly they were so intended by me when I wrote and documented
them. I don't see how "they were not meant to be" and "from my
perspetive" can be compatible, given that you were not the person who
invented this API.
A better question would be whether they _should_ be a public API. I
hope that Johannes and I have convinced you that the answer is that
(If we're going to go into historical questions, for example, in
autopkgtest 2.2.2, autopkgtest-xenlvm.deb had this description:
Machinery for setting up a Xen domain which can be resumed over and
over again, discarding changes made each time. This can be useful
for automated testing and other advanced techniques; autopkgtest is
able to make use of this machinery for its virtualisation needs.
You will need a working Xen setup to make use of this software. Your
network administrator will need to provide support for the testbeds'
networking requirements. See the README for documentation.
I'm pretty sure I had conversations with people where I mentioned this
new interface, and encouraged people to use it, but I can't find now
any reccords of such emails or other conversations.)

I think this would be a bad change for the reasons I have explained.

If piuparts requires the absolute path, rather than invoking it via
execlp, then that is IMO a bug. However, looking at piuparts in sid
it seems that it takes a command line argument and passes it to
Python's subprocess.Popen(,shell=True,). And the help messages talk

I am disappointed to see no response to the technical points I made
about PATH, and instead simply a request to you to do it his way.

I am considering referring this dispute to the TC (!)
