The point of consolidating dust is that it is the same premise as the penny jar. If you use multiple wallets, various transaction identifiers, etc, etc - You always end up with small amounts of bitcoins left over. If you consolidate them all into one wallet (AKA - the penny wallet), then one day you get a free cup of coffee.
It doesn't address any big issue, but there was a previous post about how to deal with small bitcoins left over in various wallets so I was sharing what I have done with mine.
As for dealing with wallet dust, probably the easiest way to deal with this is simply to export the keys from any/all wallets and then import them back into one wallet to consolidate your dust. It may still result in a transaction fee but at least you can keep all your pennies in one jar.
That doesn't do anything.
