That's too bad. Which use case are you running into the issue?

Given that is does not help the problem, I agree with @JonChesterfield and would prefer to first do some more experiments with the NextGen plugin and this to see its impact. If we come to the conclusion that having this is desirable, we can move it forward.
I will still update the patch with the comments.
