Shared package tech debts

[danwt]

The genesis bridge, when it goes in, will create a couple of tech debts:

• [ ] messy gerrs package hub used also in dymint
• [ ] duplicated json definitions in rdk and hub

Probably the RDK or the Hub would be a good place to move these definitions, which would introduce a dependency from repo to the other, but this is favoured by some on the team (as opposed to an entirely new repo).

I think this could lead to circular dependencies which I'm definitely against.

e.g:

1. we will require rollapp DRSs in the hub (for fraud proof) - best to avoid until we'll have more elegant solution but as a first step maybe.
2. the rollapp will require the hub (for this package)

This could get messy fast imo.

Ok I dont' have a strong opinion I do feel we need somewhere for 'shared' stuff Michael was against adding more repos

I am happy to add third/fourth/nth.. shared repos This is actually the status-quo: ie.g rdk, hub, dymint and rollapp-evm all depend on testify/ It's just the normal way of doing development
