so you select only the upstream you want, on the point you
want. And erase when someone point the problem.

Show us where Debian is using the file shipped by upstream.
Then, tell me, is Debian wrong to not use them, or
are the script shipped upstream deficient ?
In fact, you show "they are shipping initscript",
but tell me, how many of them are proper initscript,
following lsb ?
http://refspecs.linuxbase.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-generic/iniscrptact.html
As you didn't gave any link to source code,
you place extra burden on the one trying to be critics about
your argument. Maybe that's what you want, maybe not.
