That seems reasonable to me. We could modify the --preserve-env
option to take an optional list of variables to preserve. E.g.
sudo --preserve-env=VAR1,VAR2,VAR2 some command ...
Used like that it would only preserve the specified variables. If
no variables are specified, --preserve-env would behave as it does
