It’s a general comment. Manually obscured observations should remain obscured, period, end stop. The user’s wish should be respected regardless of why they have chosen to do it. There should not be any loopholes or configurations they have to further enable (to me this is just hoping the user forgets or does not know about such a configuration so you can continue to exploit the loopholes).
If you believe that an auto obscuring on a particular taxa is ‘funny’ then seek to get that taxa changed, not to allow flaws in the obscuring to remain unaddressed.
As I have written before, it is no more difficult than this, obscured should mean obscured, not obscured until someone knows how to exploit it and defeat it.
