Wow, 5 seconds is pretty aggressive! For example nginx has 60s as default, probably allowed by its event driven architecture, which mitigates some of the problems with “c10k” use cases.
Anyways, the real takeaway is even if your current solution works now, one day someone will put something stupid between your server and the clients that will invalidate all current assumptions.
For example I have created some service which consumes a very large NDJSON file over an HTTPS connection, which I expect to be open for half an hour at least, so I can process the content as a stream.
I dread the day when I have to fight with someone’s IT to keep this possible.
