let's see: when jpn/other language cards were allowed, just how many times did we event staff find translation printouts left on tables, on the floor etc. between rounds?
how many times did we find translations abandoned once pre-reg deckcheck was over, or have to hear the 'i must have lost it' at top cut check?
how many times did we have people begging for us to print out something for them that was THEIR responsibility to take care of?
how many times did we have to ARGUE about what an acceptable translation/reference was with experienced players (or their parents) who should have known better...i.e. no, that printout of a scan from *insert fansite here* is NOT a legal translation?
...way too many. oh, and let's not forget the cute little 'leave a card on the table as my "translation" even though it's not in my deck to influence my opponent's actions' trick...
good riddance to something that wasted way too much event staff time...

The problem with so many of those examples is just sloppiness of individual players:
*If you find someone's print-out, it's fairly easy to trace back to the individual, who can be punished for it.
*If a translation is lost, then the player is responsible for either finding a new one or taking several game losses in a row.
*It doesn't matter how much someone begs - just stick to the same answer ("no") and it isn't a big deal.
*Those people you were arguing with over translations are going to be as obstinate and inconsiderate no matter what policy you have or don't have. The rules were fairly explicit, so if they couldn't abide by them, then boo-hoo if they're given game losses.
All of those issues (and more) can be dealt with by a judge just putting his or her foot down. If the issue of angry poke-parents is too big a concern, then reserve re-implementation of the 10% rule for Masters only, where the majority of players are adults (or, failing that, teens who are learning to become adults).
Judges have a lot of things they need to do, and the reality of things always has to be factored in; however, even if the penalty was as severe and swift as something like a DQ, it would be worth it if we could just use these cards again. Despite all of the minor road-bumps, the 10% phase-out policy worked, and was a great balance that many players loved.
