Well, there is a point for "do what the naive user expects" rather
than "do the least invasive thing". Of course, there should be an
option for the expert to switch the behavior to the minimal thing if
he needs it.
The point is that the expert will be more likely to know that
something "special" is called for, even if this "something special"
consists in _not_ doing something.
It appears to me like the files in question might certainly constitute
something that might crop up in a naive user's workflow. Having them
get false color is not going to be a selling point, even though there
is a technical reason behind it and there _might_ be cases where the
user indeed prefers the system not interfering. But those, I think,
would be the special cases.
That being said, I am clearly out of my depth here with regard to the
technical issues involved and possible solutions, so I have to accept
the expert's decisions on them.
