Note this PR is breaking and we haven't come to a decision on whether we include it in v1.0.0 or close it and never do it.

[cmwaters]

It's breaking but I don't see much risk in making that change if we already plan on making a breaking change. At the same time, I don't think there's too much to gain

[evan-forbes]

I don't think we should merge this without either deciding that we want to hardfork the testnets and include this in v1, or add a migration script

[rootulp]

+1 we can re-open later if we want this for v2 but based on our last call, it's not making it into v1.
