Why modify b and not just balances = append(balances, sdk.NewCoins(b.Coins...))?

Why modify
band not justbalances = append(balances, sdk.NewCoins(b.Coins...))?
if we do this, we may miss b.Address.

I don't follow. We don't use b.Address. Are oldBalances being mutated?

Are oldBalances being mutated?
yes, we need to remove some zero denoms from balance of an address (occures when few denoms set to zero but not all)
ex:
{
"address": "cosmos1fl48vsnmsdzcv85q5d2q4z5ajdha8yu34mf0eh",
"coins": [
{
"amount": "10",
"denom": "foo"
},
{
"amount": "20",
"denom": "bar"
},
{
"amount": "0",
"denom": "foobar"
}
]
}
we have to remove foobar here.

tACK, thanks @atheeshp!
TEST:
Send A->B->A on 0.42, so that B has a balance entry with 0 coins. Run migration, make sure B has no balance entry.
