[address-policy-wg] PA vs PI routing pollution question

Hello! As I send a lot of PI address space requests for my customers, RIPE hostmasters often says LIR is better than PI because of "That way they can receive as much contiguous (!) PA address space as they need." When I establish a new LIR, I write almost same request for PA, and it contains same address space usage plan for two years. PI networks requested after two years are not contiguous, and I understand why. Is it means RIPE reserve some contiguous network for future grow for LIRs? If yes, how big is this reservation? -- WBR, Max Tulyev (MT6561-RIPE, 2:463/253@FIDO)
