I also would be happy for it to be locked off. I just don't believe the NZRU should just "let them have them" for the entirety of the U20 tournament under the reasoning "we do well enough without them". It would be fine for us - not so good for the Islands however. Keep in mind that in the last RWC 15 of the 30 players for Samoa were born and trained in NZ. The reality is that many of these U20 players who play for Samoa/Tonga will not make the All Blacks (which is often a first ambition), but will elect to play for Samoa, Tonga and Ireland (jokes ) later in their careers.
