I find it strange that envoy isn't mentioned in the vapor docs. If it is it's not in search. You would think there would be a little on what vapor does and does not replace. I mean there's https://docs.vapor.build/1.0/resources/queues.html#introduction
I would suggest there be a "master document" that states what can be used with what.
Example: If envoy is not to be used with vapor, or not needed with vapor. A sentence or two explaining this and why or why not.
Ditto for other laravel ecosystem items. Just a thought.
