OMG man let it go. Your posts are at the point of being unhelpful. We know there are guides out there for VPNs. That's a good solution for some people. Reverse proxies are also a good solution for some people. Yes, it takes correct setup as does anything. A warning about that is warranted, but you're well past that. A properly secured 2-factor authentication gateway (such as Authelia) along with HTTPS certs should be more than enough to secure the reverse proxy. No, not everyone will do that, but that's not your responsibility (and if you're reading this, PLEASE setup your reverse proxy with this kind of security, or consider not doing it at all).
Off the top of my head, a couple valid use-cases:
Local network only, to avoid having to remember all the ports and IPs for all your applications
Remote access where a VPN isn't viable, for instance on a work PC without admin access
In the future, please consider just answering the question, or don't respond. Thank you.
