The page to flag packages out of date specifically says it's for new updates only not for bug reports and such.

Yes, I had forgotten that.

"Please do not use this form to report bugs. Use the package comments instead. Enter details on why the package is out-of-date below, preferably including links to the release announcement or the new release tarball."

There it is, in very plain language. One would think that a person that spends a lot on time helping to maintain the AUR would have seen that. Unfortunately, it appears that some have not, or ignored it.
