The `default` pruning strategy, specifically the total number of recent blocks to keep (currently 100), was decided on completely arbitrary. I propose we change it to be enough blocks given that the typical block time is 5s and typical unbonding period is 21 days: (3600*(24/5)) * 21 = 362880. I propose this because anyone wishing to run an IBC relayer, which will be most chains, will have to be required to use `custom` to set it to this value anyway. So why not just make it the default and make it easier for operators. --- ### Author Checklist *All items are required.

I realized we should probably have a short changelog entry for this. I'll do this in a subsequent PR. |
