What? Of course there's a solution to that problem.

It was explicitly made to show 'this character has one hand' when viewing equipment to prevent people taking this solely for the mechanical benefit without actually roleplaying the fact.

If people are 'demanding others to omit the fact they don't have a hand'? Report it to the GMs if they refuse to take off the trait when it's pointed out they can't just take the trait for its mechanical benefit.

While it is a bit strange only One Handed gets this sort of treatment, it is a rather major aspect of a character whereas most other traits are things that are more subtle or pertaining to personality that's harder to objectively pass judgement on. Whether someone has a hand or not is rather objective.

EDIT: Yeah I agree with the cool guy above me. It is pretty weird to give such a powerful benefit (+5 base hit) for chopping your hand off if your build is optimal to make use of it, though that's a whole 'nother argument. Hopefully we don't get anymore traits like this that encourage munchkinning to a degree where you're tailoring your backstory for more powerful stats.
