[aur-general] Upload package blacklist, maybe upcoming merge request

Hello, I think that the package openjade1.3 [1] in AUR is badly named, and so wanted to upload an openjade PKGBUILD. But doing so burp (from git) told me this:

error: failed to upload openjade-1.3.2-2.src.tar.gz: openjade is on the package >blacklist, please check if it's available in the official repos.

(with this strange apostrophe). So I want to ask, if there is such a blacklist, and why openjade is on it. I know that there is a package jade in the repos, but that is not entirely the same as openjade. Should openjade1.3 be removed? Or merged into openjade?
