Whilst I support the goal of the proposal the current wording doesn't parse
particularly well.

By changing 'once' to 'if' and then referencing returned addresses it
(possibly) creates a confusion.

I would go with...

New IXPs will be assigned a /27 as a minimum. If an IXP requires a larger
assignment, they must demonstrate need for at least 50% of the new
assignment within two years. A maximum assignment of a /22 is available for
a suitablly qualified IXP. Any existing addresses (such as PI) used for an
IXP peering LAN shall be returned.

Feel free to butcher the text further, but I hope I've explained the reason
for the change in the change itself

Thx
