But is it a desired/final behavior?

It is possible to implement DT_AUDIT for
dlopen(), isn't it?
Many programs use plugins today, which is
dlopen() instead of a direct linking.
If dlopen() doesn't handle DT_AUDIT then
you can't provide a plugin that uses DT_AUDIT.
Is there any reason to not implement it
for dlopen?

It will likely make DT_DEPAUDIT unneeded
as a bonus. :)
