It's the same like the "Premium Product" offered since almost 2 years were a RAKICC setups a RAKEZ company and you then get the Residence Visa through the RAKEZ company.

Of course you have to pay the full amount for 2 companies the RAKICC and the RAKEZ.
As you were asking for the banking impact - it's literally 0 and just a desperate try to save RAKICC somehow.
Why?
The banks hate this structure even more then a plain RAKICC as the RAKICC is in the "Premium Product" a Holding Company holding the RAKEZ or for the aboth mentioned the RAK DED Mainland company and Holding Companies are the most difficult type of entity to open + the fact it's a RAKICC - as they fall fully into the scope of the ESR substance regulations.
Even RAKEZ is almost blacklisted from every bank since 2 years - forget about getting ENBD or something similar with a RAKEZ in 2021. And due to the RAKICC Holding that is mentione din the article aboth you even face issues getting the RAK DED Mainland company banked.
A way that has prooved to work is to setup a Dubai Company with Dubai Residence Visa and open for this structure Business & Personal Account with ENBD and using this accounts intensiv for 3-6 months + having 6 or 7 figueres with them - they consider opening for you RAKICC for Holding & Investment purpose by exception - even for RAKICC Foundation.
However from what we see in practice that's exactly not what most people looking for.
