Well, subject to the fine print, that should be okay, as I'm doing the similar thing with caddy (but not as a production server, so I haven't done any load testing). In your testing, I recommend trying large transfers (if your application ever would do that), and memory loads.
I do have a situation where I try to send (server to client) too large a file using chunks, and at some point the client sends a close before rocket expects it (still chunks to go). I'm running this on windows, and Rocket pops up a window complaining that it tried to send a 500 response but the connection is invalid ... and after a few of these, Rocket runs out of handles and things go on hold until I dismiss the popups.
