Yes i do i and you do you. But advertising those things as security measures while not adding any real security is just snake oil and can result in neglecting real security measures.
As i said, the whole internet can be port scanned within seconds, so your services will be discovered, what is the risk you assume to have when your IP address is known and the fact that you host a service with it? The service has the same vulnerabilities if it is hosted via cloudflare tunnels or directly via port forwarding on the router. So you assume that your router is not secure? Then unplug it, cause it is already connected to the router.
Geoblocking is useless for any threat actor. You can get access to VPN services or a VPS for very very very little money.
That’s an impossible task. Not even Microsoft manages that. Do not want to count how often i used libreOffice to repair or convert an older MSOffice file so it can be opend with modern Versions of MSOffice.
