Hi! Unfortunately, I don't see how that would magically spawn developers around here.

It might as well do that.
In all seriousness, it is a modern platform that a lot of people use and as Ruby siad, it will help with exposure. But most importantly the ease to find the project. The less barriers are in the way (going to wiki, regestering an account, verifying an email), the less hesitant people will be to join and consequentially participate. Not to mention all the tools Discord provides to make management of the community easy as well as sharing files and such.
You should consider it.
