Anything short of perfect order is fail, in any edition, and in any circumstance, whether in a game or real life.
Now, the houserule in question is fine and reasonably balanced ... just ... it, and any other housrule, must be implemented, transparent, and fully understood before the character creation process.
And in so doing, assuming all parties involved are sufficiently intelligent, you have perfect order.
Now, I acknowledge that truly lawful (read: mechanical) people are quite rare, and so rather than have unrealistic expectations, I will simply be magnanimous and accept others' inevitable failure.
