Is there still a need for Messaging Frameworks or is a RabbitMQ abstraction good enough?

cross-posted from: https://feddit.org/post/21212856

We are setting up a new project right now, where we want to implement Messaging. We usually would just add MassTransit and call it a day. Since they went commercial, we are asking ourselves the quests if there is still a need for Messaging Frameworks, or if a self written RabbitMQ implementation is good enough for most cases?

What are your opinions on that?

Are you still using a Messaging Framework, if so which one are you using and why?

Or are you just writing your own implementation with RabbitMQ, if so do you see any problems with that approach?
