This looks great. Nice work.

can we uncomment the sims runner now? or is there more to do after this?

Genesis simulations are still using v1alpha2. We can enable sims after we migrate genesis state to v1 api #977.

[aaronc]

why do we still need this legacy function?

[ryanchristo]

We need to finish migrating genesis from v1alpha1 to v1 (see #976). @aleem1314 can you make sure we remove the use of legacy types here in the genesis simulation with the changes in #977?
