GLOP was only ever experimental to start with, and is not relevant to 
SSM - hopefully Max you're not using ASM.

I don't think there was ever any scope to include it in the RIR 
assignment mechanism, and given that it breaks with ASN32, its status as 
experimental + lack of support in the RIRs are unlikely to change in future.
