`port destroot` does not actually install anything, so no. And `port upgrade` preserves the variant selection of the currently-installed port, while the other subcommands do not.

>> Single-dash single-letter flags like "-f" are "global" and have no effect unless placed after the word "port" and before the command verb (e.g. "sudo port -f uninstall"). Double-dash multiple-letter flags like "--force" are specific to the command verb in question, so they must be placed after the command verb and before any subsequent arguments (e.g. "sudo port -n upgrade --force").

If that's the case, it's a bug in port(1)'s option-parsing, and you should not rely on it.
