[db-wg] Support for expansion of an origin into a list of prefixes

Dear RIPE DB-WG, Much like my previous request regarding server side expansion of objects, I'd very much like the RIPE Database team to implement two flags which IRRd currently supports: !g & !6 I've filed an enhancement request on github: https://github.com/RIPE-NCC/whois/issues/73 The !g and !6 flags signficantly reduce the amount of RPSL interpretation a client has to perform, as the server provides the clients with a straight answer (abeit simplified). If the DB team implements such a feature, I'd also very much like an implementation in context or RDAP so I can query for lists of prefixes through HTTP rather than WHOIS. Kind regards, Job
