It's certainly something to bear in mind...in my opinion, Graal needs to be able to put its best foot forward before submitting to review; Graal should be able to say "Here's your account, here's the homepage if you have any questions, you can get live support from the FAQ guild if it's really tricky; please join us this saturday for the annual sparfest and barbeque on Valkorlia, it should really be most splendid." As it stands, it seems to me any reviewers would be well advised to wear a hardhat.
It's nothing that would necessarily take years and years to get together either...take maybe a month to tidy up loose ends on all the servers while contacts are gathered - have everyone cordon off the work areas, etc. - then release the reviewers. Restaurants do it all the time when the health inspector's showing up.
