No one. The only spots that are reallocated are the ones from Groups A-C in the general JGP Announcement.
Group A - member federations ranked 1-3 at Jr Worlds (JPN, KOR & USA) - 2 spots in each JGP = 14 spots for each member
Group B - member federations ranked 4-6 at Jr Worlds (FRA, GEO, EST) - 1 spot in each JGP = 7 spots for each member
Group C - member federations ranked 7-10 at Jr Worlds (SUI, AUS, FIN, CHN) - 1 spot in 6 JGPs = 6 spots for each member
None of those countries are relinquishing any of their spots.
