This doesn't really fix the problem. Curl is not the only tool to have implemented this block, many tools have, this was the point of Tor requesting this mechanism via an RFC. Is oniux going to set hundreds of environment variables to deactivate the block in all programs they know about? And cause users to send bug reports to all programs complying with their RFC that their tool doesn't yet know the workaround for?

The fix is much simpler: have oniux set $http_proxy (and drop non-tor traffic). This is the mechanism that makes the more sense and is in line with their own RFC.
