Yup. If the script is stable (as in sort stable), anyone running it
locally will get the same results as upstream and each other.

I think it's even less important than that. Bisecting will work
*better* when using submodules than it does using SVN (because git
bisect is more powerful, allows me to track all modules' history, and
will rid me of a complicated downstream set of SVN-bisect scripts).
The only thing we *have* to have a sequential number for, are
releases. Even that can be ran manually.
We agreed to have sequential numbering from the start to allow
infrastructure to migrate slowly to a Git model. That can also have an
extra step to run the script if IDs are not populated yet.

Whoever maintains the current infrastructure, which is currently the
Foundation. All scripts will be upstream.
So far, they (Tanya, Anton, Galina) have been very responsible to
every downtime and problems I found. I have no doubt that this will
continue to be a trend.
