I probably spent more time on word-completion than on pretty much any
other part of minibuffer.el, so believe me I've thought about what is
word completion and my understanding of it is embedded in the current
behavior (which is very similar to partial-completion-mode's behavior).

So, no I am not "de mauvaise foi", I really honestly do not understand
how you want to interpret the above "definition" of word completion in
the context of partial completion.  There are many different ways to
interpret it, probably.  But none of them seem to match the behavior you
seem to want in your example.  So unless you explain to me what behavior
you generally expect (at least with more examples), the only answer
I can give you is "your word completion seem to dislike partial
completion, so you'll need to disable partial completion", which your
report said you did not consider as a good answer.
