I don't think that I can agree with you.
At best, the system might prevent what seems to be extremely rare abuse of a bug that nearly no one knew about, before the system was created.
If this was true, I guess that the system would have never been added. Let me provide some background.
The abuse of this bug was spotted at least 1.5 years ago for the first time. In the beginning it was performed by a single person. It was annoying, but, as you say, it was not really a big deal, however, Mia and I developed two independent fixes for this bug shorty after we had witnessed it. Eventually the aforementioned person ceased to play here and the fixes had never been added that time.
The issue became topical again a few months ago when this bug was noticed to be abused regularly again by different players, even without the "zero patient". The problem required either a program or a legal solution, and the program one already existed, so we only needed to hunt it out; Mia and I merged our code, which seemed to have worked the best, and upon further testing and improvement it was added to the server.
(On that note, if the system is removed, I'm all for obscuring past posts about the bug to prevent abuse.)
Also, that's why the "security via obscurity" will not work.
...and it didn't really interfere with gameplay nor give much of an advantage. It was a "wow, this person is an idiot" *moves on to President* moment.
As much as you're right that it doesn't really interfere with PTP gameplay, the reality is that the common onfoot fights are an integral part of the gamemode. We can't simply disregard it. Players want fairness, and this is a foundation stone of the policy of the administration; unlike real life, it can be achieved here (within reasonable limits). The realization of the fact that anyone can survive in a fight performing this bug feels extremely unfair. Why to put any efforts in the game if a rival can just hit "F" and nullify them? That's the same reason we have the rule about death evasion. Is it a big deal that your enemy quits the game in front of the last bullet destined to finish them? No. But it feels as unfair as, say, hacking.
That's why I think that we should keep the system, fixing and improving it again. Please, state what exactly causes your dissatisfaction. Explain us what should be corrected, and we'll do our best to make the system optimal. So,
-1.
For last, please note that it is just my subjective opinion over the issue.
