If we're really minimalizing something this small

for name, id in pairs{
    Oondasta = 32519,
    Galleon = 32098,
    Nalak = 32518,
    Sha = 32099
} do
    print(name, IsQuestFlaggedCompleted(id))
end

/run for k,v in pairs{Oondasta=32519,Galleon=32098,Nalak=32518,Sha=32099} do print(k,IsQuestFlaggedCompleted(v)) end

Returns true or nil based on completion status, good enough for many.
