Yes they can, but if they are really interested to make their LIR job. If the only motivation of new-comers is to get some IPv4 as their internet service provider is not able to provide them with any, there would no do LIR job. (new RIPE NCC members are not necessarily from IT industry and are forced to become LIR)
Why wouldn't a LIR get some space on the secondary market to provide to its customers ?
And you consider it fair when you cannot get more than /22 when some players have /19 or more?
For some definition of "fair". I came to the game later when the pool was empty, I know it and I understand it. So, I consider "fair" I was able to get a small part of IPv4 that helped me kickstart the business.
At the moment many new LIRs are just joining the RIPE NCC to get small blocks, that is happening.
Some are taking advantages of this situation (open multiple LIR) to get IPv4 space. I don't see how 2015-05 would stop that even if you allow new LIR to get more than a /22. All I can see it more faster depletion (honest LIR getting more + dishonest LIR getting more) I hear your arguments but I don't think 2015-05 is the right answer for the community. Denis
