Definitely one of the best features to have this in the native UI, though it's also possible in other ways
If anyone wants this without GrapheneOS: https://f-droid.org/packages/dev.ukanth.ufirewall
If anyone wants this without GrapheneOS and without root: https://f-droid.org/packages/net.kollnig.missioncontrol.fdro...
That's not at all a similar approach so it doesn't quality as "if anyone wants *this*). The GrapheneOS feature pretends the network is down and local host is also inaccessible. This is good for compatability (apps generally take into account that a network can be down) and too avoid apps knowing you are using the feature.
