Non-HTTP on IPv4

Is it possible to serve a TCP port that isn’t HTTP? For some reason I thought this was possible, but when I specify the following services.ports configuration, I get the following error.

  handlers = ["tcp"]
  port = 5000
Error Services [0] Ports [0] Handlers must be one of: tls, http, proxy_proto, edge_http

:man_facepalming: I re-read the docs, and I see now I just need to omit the handlers to have TCP pass-through. :tada:
