There’s also other reasons to run a reverse proxy! Like for instance “you want to run multiple web services, but they’d both need port 443 and clobber each other”. So you can stick the reverse proxy on port 443 and then have it pass stuff to your various backends.
That’s actually a situation where you could avoid the reverse proxy with more machines (one per service), rather than less!
