Placeholder notes / Don't publish dead links

What I’m trying to do

As I write a blog post, I find myself wanting to “link out” to posts that don’t exist yet. I’ll type a phrase, and realize that it would make a great post of its own, but I don’t have time to research & write it now.

The bad part is, these end up as dead links when publishing.

I guess this is a feature request, but I thought I would start here and see if there’s a way already built in to achieve what I’m trying to do.

Thanks!
