Either you think that the broken hash is serious enough to merit a
stopgap, or you think it's not serious enough. There is really no way that
it can be a serious problem in Sage 6.10, but not a serious problem in
Sage 6.9.
It makes procedural sense because then people working on development will
have a signal and an incentive to do something about relying on the bad
hash. We are currently in a situation where we won't ever catch up,
because people are adding new classes depending on the default hash at the
same rate as we're trying to fix it (see the recently merged
`sage.combinat.colored_permutations`). Those people should get a signal
that they shouldn't be depending on that to-be-deprecated hash. The
difference is that now we have a good shot at resolving this whole thing
before releasing 6.10, whereas this issue received attention too late in
the 6.9 cycle for that to be realistic.
