I am almost sure that this was not the intent of the changes and having said that changes will need to be deployed after a while. Steemit released a statement before the Hard fork that the witnesses could have an alternative to revert to the prior system as well. I see some of the benefits as spamming will be leas likely and it will ultimately lead to better scaling but agree with your assessment that it will be at the cost of smaller accounts who should have the ability to transact more to grow quicker. I am hoping that these RC costs scale down to the size of the SP because the new and small accounts are the future to this platforms success and if we are creating an ecosystem with various methods of engagement, we should also provide the bandwidth to do so.
