Hello kylerollins.
Posts2Posts is a required plugin. To make some of the connections between Companies, Projects and people.
I was surprised to find you were correct about Posts2Posts. I don’t feel like it would be a problem though. The plugin has a large enough following in its community that any major problems that would arise out of Major Revisions in WordPress would be fixed.

He has stated in his blog post that while he won’t be working on it anymore, it is for the reason that
since the plugin already works well enough on the single site where I use it.
We have used posts2posts extensively on the many websites we have made and feel there would be no major problems.
In the same blog post, while he did say he wouldn’t be developing on it anymore, he will accept pull requests from the community
Of course, I’d be happy to review and merge pull requests that people open and still hope that I’ll eventually be able to hand it off to someone else.
Perhaps someone would pick it up, perhaps not, but I don’t feel there would be too much concern about the plugin dying.

Thanks for your reply. Until someone picks up responsibility for Posts2Posts, it does not meet our internal requirements and we unfortunately cannot use it. I will continue to use it in our dev environment and hope someone will pick it up as it seems to be just what we want.
You might want to look at Types. It also manages posts-to-posts relationships, although with a GUI and probably in a more complex way than Scribu’s. Neverheless, it’s an alternative, with active development and use.
