Soon we will get address space of around /10 from IANAs returned pool 
plus the reserved we already have.

Sustainable for a long time...this a tricky question. What is "long 
time"? Are we planning to still working in IPv4 in, lets say, 5-10 
years? If yes, and in 5-10 years IPv6 isnt the main internet protocol 
all we, as LIRs, will have a very big problem.

Growing to a /8 could take several years. And not every LIR with one /22 
will need a second /22.
