Not a good idea - a lot of the 3rd party tests that depend on dict
ordering are going to be using those modules anyway, so scattering our
solution across half the standard library is needlessly creating
additional work without really reducing the incompatibility problem.
If we're going to change anything, it may as well be the string
hashing algorithm itself.
Changing the string hashing algorithm will hit the general performance
and also will break down any code that depend on dict ordering.
Specialized dict slow down only needed parts of some applications.
The minimal proposed change of seeding the hash from a global value (a
single memory read and an addition) will have such a minimal performance
effect that it will be undetectable even on the most noise-free testing
environment.
Cheers,
