My question went unanswered but from how I see it.
They think/know there is a POS glitch where someone can get POS more frequent than normal so they create these wallets but don't make it mandatory (hard fork) to update wallet.
Why would anyone update?
I think you're misinterpreting the update.
Those wallets don't fix the issue they are proof of the issue. If you use either of those wallets you should in theory stake faster than you would using the normal wallet.
