Nah, they’re shutting off port-forwarding because there were probably a bunch of users abusing the service and using it to distribute CSAM, and they got tired of having law enforcement at their door. Port-forwarding itself isn’t inherently bad, but when it’s used for that purpose it is.
The 2 main things keeping me on X11 is G-sync not working and a sleep bug. I really hope these get fixed soon
