Hello,
I think it is beneficial for RIPE to change the model because 2022 showed that in the long term, the current model doesn't have a future. Reserves will be exhausted or the fees per LIR account will have to be increased significantly.
Also, it would be interesting to hear how this new charging scheme model would affect the current IPv4 waiting list. Now the members have to pay sign-up fees and yearly fees without receiving resources. How these members (that are still waiting in a list) will be charged after implementing this new model? And how new members applying for resources would be charged?
