Problem is that the ctte does not consider this issue unless there is a
technically feasible solution available.
You mention systemd-sysv, I was talking about the new init package.
What's wrong with modifying that package?

A solution in sid has much more time to be discussed and mature.

So you are saying that adding a debconf prompt to the new init package
is not possible. Where to have such a test then, apt/aptitude, before
starting a dist-upgrade??
