I don't see that at all. I see the logical extension of the games mechanic. You must take the good with the bad. If you have a bounty, any other BH must verify your their target. Giving you time to get off the first shots.
The logical extension of BROKEN mechanics perhaps but you're trying to promote simplicity and unfairness over what any sane and normal person in the real world would expect.
Scoring bounties off of NPCs shots is NOT the same as getting charged with murder (with a 5+ day cooldown) over an errant / premature 'graze' (NOT kill shot) of a wanted criminal.
Objectively, I get your point but subjectively, it's stupid.
