ignore locally installed packages when importing

Oooh, fair point! I didn't consider this case, for sure.

Implementing the very basic fix / feature for this will very probably require additional parsing of the $CARGO_HOME/.crates.toml file done in order to save the in-parenthesis source. An enumeration should represent this well. The part before the + will probably be the variants and after an associated URL. Checking all the possible source values in some documentation or source of Cargo should still be done in order to ensure nothing was forgotten, however.

Then, from a feature point of view, at the very least the change should be reflected by adding a mention of the filtering in the command's documentation comments so end users may see it from the usage messages. Beyond that, you can either let it be something always done in a hard-coded fashion, or additionally implement a new CLI option in order to force keeping the local-only installs in the resulting table. In the second case however, the default would still be to filter them out. I usually do this when implementing such a breaking change so end users may choose for themselves while still ending up with a sensible default.
