As far as the ACLs, I think Windows Explorer uses this technique, so if
it causes problems with scanners, these problems happen just working
with files in Explorer too.

It is more complexity, but you could check if the 'attributes' are
incorrect and only make the API call if there is something to change.
Thus, only those users affected by the problem incur any decrease in
performance.

(This is assuming the API's in question are not already optimized for
this case; if I recall correctly, I don't think these kinds of APIs edit
the modified date in any case, for example.)
