Minnows such as Brazil and Samoa will benefit from playing at the World Cup despite suffering a series of heavy defeats at the tournament, says World Rugby.
Brazil, the lowest-ranked team at the tournament, were beaten 84-5 by France on Sunday after a 66-6 loss to South Africa in their opening match.
Samoa have conceded a total of 165 points and scored only three in their matches against Australia and England so far.
However, Sally Horrox, chief of Women's Rugby at World Rugby, says such scorelines will happen with teams at different stages of professionalisation.
