It is usually better to add new params at the end, unless there is a reason.

there's a reason, progress callback was added right after callback argument, unfortunately, it also caused a collision with this "private" argument

if (!options || !options.disabledDirectory || !options.apiVersion || !options.systemExtensionDirectory) {
callback(new Error(Errors.MISSING_REQUIRED_OPTIONS), null);
return;

Does this actually make a difference?

I'm assuming the intent was to prevent similar bugs in the future: if you accidentally pass an extra callback arg in this position, it's truthy but not === true.

That said, silently acting like the param was false doesn't necessarily mean we're preventing the mistake from causing a bug. Might be nice to have something like console.assert(_doUpdate === undefined || typeof _doUpdate === "boolean") at the top if we're truly worried about this problem happening again.

Or the other option would be to add a unit test that covers this, so that regardless of what breaks it we'd find out via a failing test :-)

if (hasLegacyPackage) {
// When there's a legacy installed extension, remove it first,
// then also remove any new-style directory the user may have.
