In my mind, "1.0" for Scipy means that we cover a basic set of features
needed for numerical science, and do it well. A definition via negative
is: at "1.0" we don't have
(i) stuff that's obviously crap
(ii) blank spots at commonly needed functionality
(iii) awkward usage patterns
It is of course a subjective matter what this means, but writing the
known issues down in the roadmap is one way to define it.
Regarding API deprecations: I think breaking a lot of stuff at "1.0" at
once is not a good idea, and I don't think that will happen. Rather,
things progress as we have done so far --- if something is horribly
awkward, a new API is introduced and the old one is deprecated. We can
perhaps be slightly more aggressive in the cleaning out crap at "1.0",
but I don't think there'll be a qualitative difference. This is also for
practical reasons, as we will not be able to fix everything in one go in
Rather, one day in the distant future, it turns out that the next
release is in a good enough shape to be called "1.0". The "0.x" roll up
to that point.
