pools need some time to compile the wallet... and recenltly... most wallets miss some dependencies... its not just writing a command and wait for it to compile...its like as if everytime you have to learn everything from the start... everytime a small "something is missing" and you cannot compile...
if the pools cannot have tha wallets, well its like no launch...
That's pretty dramatic...
There's a low block reward to begin with, that gives the pools plenty of time to do what they need to do and people time to register and move their rigs over.
