You could make that switch active only in the scratch directory and, ...

... I would be fine with removing -Werror in released tarballs because I
feel that this increases the robustness of the released tarballs in
compiler version variations.

I should point out, though, that this kind of scheme (the deprecated
attributes) where you try to delay user pain is nothing but that: the
addition of a delay and experience shows that users usually ignore all
the big red warnings you print and usually start complaining when the
"deprecated" code starts disappearing, even years after the addition of
the "deprecated" keyword.
