Will redeploy it with a newer compiler version to both networks. Thinking about whether it would make sense to deploy it to APM as well so we have an immutable reference to the default PPF.

Maybe if we meant to use proxies on top of it (which may make sense), otherwise the "default" one would be A1's?

I was thinking ppf-factory.aragonpm.eth for factory and then ppf-a1.aragonpm.eth (it would be even better if we got an a1.aragonpm.eth registry for us actually!)

[sohkai]

I like both of those (ppf-factory.aragonpm.eth and a1.aragonpm.eth) ❤️
