On the other hand, breaking many API users isn't good either.

However, endlessly arguing which of these is the lesser evil isn't
getting us anywhere.

The best way forward is to get API users fixed.
Thus I'll try to fix all affected packages in Debian, but I don't know
how much time that will take.

I suggest that we table the discussion until sometime closer to the
release, maybe in a month?

If most packages are fixed by then, this API could be removed,
otherwise it might be better to delay it's removal (or the release).

Best regards,
