One such discussion is here:

We can do so now either by "blaming" one and finding the originating
commit, or by searching for "support fetching unadvertised objects" (I
used the same comment everywhere in the commit [1] so that people can do
this), but I don't know how to enforce this for future work. (We can add
a special variable, but I think it's unnecessary and we can't enforce
that people use that new special variable instead of
GIT_TEST_PROTOCOL_VERSION anyway.)
